Juneyao A321 Hard Landing: How a 3.06G Touchdown Triggers an A321 Structural Inspection

Collector Feature · April 2026

On April 9 2026, Juneyao Airlines flight HO1249 from Shanghai Pudong to Chongqing Jiangbei recorded a first-touchdown vertical load of +3.06 G. The Airbus A321-231 (registration B-1006, MSN 7926, delivered October 19 2017) bounced and made a second contact at +2.12 G before coming to rest normally. No injuries were reported. The following day's return flight HO1250 was cancelled; Civil Aviation Administration Southwest Regional Bureau (CAAC Southwest) opened a formal investigation on April 14. Airbus A320-family Aircraft Maintenance Manual Chapter 05-51-11 sets 2.6 G as the mandatory hard landing inspection threshold and 2.86 G as the severe hard landing threshold—B-1006's first contact exceeded both limits.

B-1006 is one of 41 A321-series aircraft Juneyao operated as of February 2026—27 A321ceo and 14 A321neo—out of a total fleet of 103. The A321 is the airline's high-frequency trunk-route workhorse, and the type carries a disproportionate share of Juneyao's special-livery programme: since 2023 four distinct full-fuselage schemes have been applied across three A321 registrations. This article covers the HO1249 incident in technical detail, then documents those liveries and the diecast models that record them.

Understanding the 3.06 G Event: What Happens to an A321 Structure

A standard Airbus A321 approach aims for a vertical load of 1.0–1.4 G at touchdown. Airbus defines four load bands for the A320 family: Low (>1.5 G), Medium (>1.6 G), High (>1.75 G), and Hard Landing Check (≥2.6 G). At 3.06 G, B-1006's first contact was in the "Severe Hard Landing" band—the highest tier, requiring inspection of main landing gear attachments, wing lower skin panels, and fuselage frame Station 34 through 53 before the aircraft is returned to service. The bounce that produced the second 2.12 G contact is categorised in accident-investigation terminology as a porpoise: a longitudinal oscillation following an excessively firm initial touchdown, typically caused by high approach speed, float above the threshold, or late flare. CAAC Southwest's investigation will determine the contributing factors specific to HO1249.

B-1006 was 8.5 years old at the time of the event. It entered service with Juneyao Airlines on October 19 2017, ferried from Hamburg XFW via TSE. Since delivery the aircraft has operated exclusively within Juneyao's narrow-body network covering Shanghai, Chongqing, Chengdu, and over 60 domestic points.

Juneyao Airlines: From 2006 Launch to 103-Aircraft Fleet

Juneyao Airlines (吉祥航空, IATA: HO, ICAO: DKH) commenced operations in September 2006, initially with a small A320 fleet out of Shanghai Hongqiao. The airline is privately owned by the Juneyao Group conglomerate and is headquartered at Hongqiao International Airport. By February 2026 the network spanned 93 Airbus A320-family aircraft and 10 Boeing 787-9 Dreamliners, making Juneyao the largest A320-family operator in China after Air China, China Eastern, China Southern, and Sichuan Airlines. The A321 forms the high-density trunk-route core; the 787-9 operates international routes to Tokyo Narita, Osaka, Seoul, and select European destinations.

Juneyao is distinctive among Chinese carriers for its high-profile special liveries. Since 2020 the airline has commissioned bespoke full-fuselage artwork for commercial partnerships including Legoland Shanghai Resort (two versions on B-9957), Genshin Impact (on 787-9 B-209R), and a jellyfish-themed design for B-32CJ. These liveries are documented across the NG Models and JC Wings 1:400 programmes below.

Legoland Shanghai Livery v.1 — A321-231 B-9957 · 1:400

Juneyao Airlines placed the first Legoland Shanghai Resort special livery on A321-231 B-9957, likely in late 2023 ahead of the resort's commercial opening. The livery wraps the lower fuselage with a continuous mural featuring a green dragon, a brown King Kong-like figure climbing Lego brick architecture, and the text 上海乐高乐园度假区 (Shanghai Legoland Resort) in blue above the mural. The nose-to-tail artwork runs below the window line, while the all-yellow fuselage and yellow vertical stabilizer carry the classic Juneyao "phoenix double" emblem in off-white. Engine nacelles are painted sky blue with a "LEONARDO" brand marking—an airline partnership identifier. Sharklet winglets carry a blue tip with a white Juneyao "J" roundel.

NG Models cast NG13132 captures the full-fuselage mural in 1:400, including the blue engine nacelles and blue sharklet tips. The model records the livery version with the "LEONARDO" nacelle marking—a detail unique to this specific operating period of B-9957. NG13132 is the only commercially available 1:400 diecast documenting B-9957 in the first Legoland Shanghai configuration.

Aircraft record — B-9957: Registration B-9957 is an Airbus A321-231 in Juneyao Airlines' narrow-body fleet. The aircraft entered the Legoland Shanghai livery rotation as part of a multi-year partnership agreement between Juneyao Group and Legoland China, which opened its Shanghai resort in 2024. B-9957 is one of two registrations to carry Legoland-themed artwork.

Legoland Shanghai Livery v.2 — A321-231 B-9957 · 1:400

The second Legoland version on B-9957 retains the yellow fuselage base and yellow tail but revises the lower-fuselage mural: the King Kong figure now rides a wave or cloud motif, and additional Chinese text 萌趣可乐 appears in the design. The green dragon near the nose is also present but repositioned. Engine nacelles remain bright blue with a white brand logo. The principal visual difference from v.1 is the revised cartoon character posture and the altered mural framing below the window line—making this a separate diecast collectible from NG13132 despite sharing the same registration.

NG13141 captures the revised mural geometry and the altered character arrangement below the waterline, distinguishing it from NG13132 in a side-by-side collection display. NG13141 is the only 1:400 diecast recording the second-version Legoland mural on B-9957; no other manufacturer has released this configuration at any scale.

Aircraft record — B-9957 (continued): Operating both livery versions on the same airframe gave Juneyao flexibility to repaint between seasonal park campaigns. Aviation enthusiasts documented the transition between versions on Chinese aviation forums in mid-2024.

Jellyfish Special Livery — A321neo B-32CJ · NG Models 1:400

Registered B-32CJ, this A321neo carries one of Juneyao Airlines' most elaborate special schemes: an underwater-scene fuselage mural populated with jellyfish in pink, purple, orange, and yellow against a white base. The vertical stabilizer is deep red, bearing the airline's gold phoenix emblem. Engine nacelles are also deep red with a small gold roundel on the cowl. Sharklet tips are red, with 吉祥航空 marked vertically on the inner winglet face. The mural extends from above the wing trailing edge to the tail on both sides of the fuselage, while the forward section remains white with red "JUNEYAO AIR / 吉祥航空" titles. The registration B-32CJ appears on the aft fuselage above the mural and on the underside of the left wing.

NG13087 reproduces the multi-tonal jellyfish mural at 1:400, with the red tail, red engines, and red sharklet tips forming a consistent accent colour against the white base. The model also records the "BIENA" branding mark visible below the cockpit windows—a commercial partnership logo present during the livery's initial deployment. NG13087 is the only 1:400 release of B-32CJ in the jellyfish configuration from any manufacturer.

Aircraft record — B-32CJ: B-32CJ is an Airbus A321neo delivered to Juneyao Airlines, operating on the airline's medium-haul domestic network. The same registration was subsequently captured in a different special livery by JC Wings (LH4333), making B-32CJ the only Juneyao A321neo to have two separate 1:400 diecast releases in different liveries.

Standard Red Livery — A321neo B-32DF · NG Models 1:400

B-32DF wears Juneyao Airlines' production standard livery for the A321neo fleet: white fuselage with red "JUNEYAO AIR / 吉祥航空" forward titles, deep red vertical stabilizer with gold phoenix emblem, deep red engine nacelles with gold roundel, and red sharklet tips. A sparse scatter of small red-orange dots appears below the window line on the mid-fuselage—a low-profile design element that distinguishes the neo standard livery from the earlier ceo fleet. The registration B-32DF appears on the vertical stabilizer leading edge and on the aft fuselage below the window line.

NG13088 documents the baseline neo livery as initially applied to the early A321neo deliveries, including the dot scatter detail and the production-standard gold phoenix tail. As the A321neo fleet grows towards and beyond 14 aircraft, this standard configuration will represent the dominant livery variant in Juneyao's narrow-body fleet. NG13088 is the only 1:400 diecast of B-32DF at any scale in current production.

Aircraft record — B-32DF: B-32DF is one of Juneyao Airlines' A321neo deliveries, operating primarily on trunk routes between Shanghai Hongqiao and western China domestic points including Chongqing and Chengdu—the same route pair at the centre of the HO1249 event.

Floral Special Livery — A321neo B-32CJ · JC Wings 1:400

JC Wings captured registration B-32CJ in a completely different special livery: a cherry-blossom-inspired floral scheme covering the lower and mid rear fuselage. The base colour transitions from light pink to deeper pink-purple towards the tail, overlaid with intricate floral artwork in purple, yellow, and white. Forward fuselage, nose, and upper surfaces remain white. The red tail and red engine nacelles carry the same gold phoenix emblem as the standard livery. Sharklet tips are red. The floral artwork sits below the window line on the rear fuselage, blending visually with the red tail assembly.

LH4333 records the floral livery phase of B-32CJ's operating history, distinct in design language from the jellyfish scheme (NG13087) applied to the same registration. Pairing LH4333 with NG13087 documents two separate real-world repaint events on the same airframe—a collection narrative unavailable from any other Juneyao A321neo registration. LH4333 is the only 1:400 diecast of B-32CJ in the floral livery configuration; combined with NG13087 it forms the only two-livery single-registration A321neo pair in the Juneyao diecast catalogue.

Aircraft record — B-32CJ (continued): B-32CJ's multiple livery sequences reflect Juneyao's active partnership-marketing programme. The airline has used special liveries as paid commercial placements since at least 2020, with individual aircraft rotated through schemes tied to product launches, tourist destination campaigns, and media properties.

1:500 Scale Reference — Boeing 787-9 B-1115 · Herpa 1:500

Herpa produces its commercial airliner programme almost exclusively at 1:500 and rarely selects Chinese domestic carriers for the catalogue. The HE533089 release of Juneyao Air's Boeing 787-9 is one of the few Chinese-registered widebodies in the Herpa 1:500 line, making it a structurally different type of acquisition from the NG Models and JC Wings 1:400 releases above. The model carries registration B-1115 in a peony floral special livery: a white fuselage base with a large multi-coloured peony mural covering the lower rear fuselage in blue, purple, yellow, and burgundy red, with stylised cartoon-face flowers integrated into the design. "DREAMLINER" appears in dark text above the mural on the aft fuselage. The vertical stabilizer is deep burgundy red with a large gold phoenix medallion; engine nacelles match the burgundy red with a small gold roundel at the cowl face. Raked wingtips carry a burgundy red tip band. The forward fuselage reads "JUNEYAO AIR / 吉祥航空" in burgundy above the window line.

HE533089 is cast at 1:500, making it physically smaller than all five A321 entries above and placing it in a separate display tier. At 1:500 the 787-9 measures approximately 13.5 cm in length, compared to roughly 9 cm for a 1:400 A321—the scale difference is visible when the two types are shelved together. HE533089 is the only Herpa release of any Juneyao Air aircraft in current production, and the only 1:500 diecast of a Juneyao 787-9 from any manufacturer.

Aircraft record — B-1115: B-1115 is a Boeing 787-9 Dreamliner in Juneyao Air's widebody fleet. The peony livery is a standalone decorative scheme unconnected to a commercial partnership—distinguishing it from the Legoland and Genshin Impact placements on the A321 and 787 registrations documented elsewhere in this guide. Juneyao's 787-9 fleet of 10 aircraft operates international routes including Shanghai–Tokyo Narita, Shanghai–Osaka, and select European services.

Entry collection (2 models): NG13132 + NG13088 document the A321ceo Legoland special and the A321neo baseline—covering both sub-types of the Juneyao narrow-body fleet, which includes the event aircraft B-1006's airframe type.

Special-livery pair (2 models): NG13087 + LH4333 pair two separate real-world liveries on the same registration B-32CJ. This is the only Juneyao A321neo registration with two distinct 1:400 diecast releases, making the pair a physically verifiable two-livery single-aircraft display.

Complete set (5 A321 + 1 Herpa 787-9): All five A321 entries span the ceo sub-type (two Legoland versions on B-9957) and the neo sub-type (jellyfish and floral on B-32CJ, standard on B-32DF), forming a continuous record of Juneyao's A321 special-livery programme from 2023 through 2025. HE533089 (Herpa 787-9 B-1115, 1:500) adds a scale and brand dimension unavailable in the 1:400 programme: it is the only Juneyao aircraft in the Herpa catalogue and the only 1:500 entry in this guide. NG55122 (787-9 B-209R, Genshin Impact, 1:400) is listed in the table as a reference entry; a dedicated guide to Juneyao's 787-9 fleet is published separately.

FAQ

What is a hard landing check on an Airbus A321?

A hard landing check is a mandatory airframe and landing gear inspection required by Airbus A320-family Aircraft Maintenance Manual Chapter 05-51-11 when vertical load at touchdown exceeds 2.6 G. For loads at or above 2.86 G (designated "Severe Hard Landing"), the inspection scope extends to main landing gear attachment fittings, wing lower skin panels, and fuselage frames between Station 34 and Station 53. The aircraft is grounded until the inspection is completed and signed off.

Did the HO1249 incident on April 9 2026 exceed the severe hard landing threshold?

Yes. The first touchdown of B-1006 on flight HO1249 recorded +3.06 G, which is above both the 2.6 G hard landing threshold and the 2.86 G severe hard landing threshold defined in the Airbus A321 maintenance manual. The second contact after bounce was +2.12 G. CAAC Southwest Regional Bureau opened a formal investigation on April 14 2026.

What is registration B-1006 and when was it delivered?

B-1006 is an Airbus A321-231 (WL), MSN 7926, delivered to Juneyao Airlines on October 19 2017 from Hamburg XFW. At the time of the HO1249 event on April 9 2026, the aircraft was approximately 8.5 years old. The A321-231 designation indicates the CFM56-5B-powered variant of the A321ceo.

How many A321s does Juneyao Airlines operate?

As of February 2026, Juneyao Airlines operated 41 Airbus A321-series aircraft: 27 A321ceo (A321-200) and 14 A321neo. Total fleet including 787-9 was 103 aircraft. The airline does not operate the A321XLR, A321LR, or A321ACF variants.

What is a porpoise in aviation landing terminology?

A porpoise is a landing oscillation in which a firm initial touchdown causes the aircraft nose to pitch down, driving the main wheels back into the runway and producing a series of bounces. On flight HO1249, the first 3.06 G contact caused B-1006 to become airborne again briefly before a second 2.12 G contact. The term derives from the resemblance to a dolphin or porpoise breaching the water surface repeatedly.

What is the difference between NG13087 and LH4333 if both are A321neo B-32CJ?

NG13087 (NG Models) captures B-32CJ in the jellyfish special livery: underwater-scene mural, white base, red tail and engines. LH4333 (JC Wings) captures the same registration in a later floral special livery: pink-to-purple gradient rear fuselage with cherry-blossom artwork. Both record different paint phases of the same physical aircraft, making them complementary rather than duplicative releases.
