Boeing 787 Dreamliner — Safety Profile
Twin-aisle widebody · First flight: 15 December 2009 · EIS: 26 October 2011 (ANA) · Updated 20 May 2026
The Boeing 787 Dreamliner is a wide-body twin-engine long-haul aircraft built around a composite fuselage, electrical (not bleed-air) architecture, and high-bypass GEnx or Trent 1000 engines. Variants: -8, -9, -10. The type was grounded worldwide for around three and a half months in 2013 following two lithium-ion battery thermal-runaway events; the battery enclosure was redesigned and the fleet returned to service. As of 2026, more than 1,100 Dreamliners are in service across most major intercontinental carriers. The June 2025 accident involving Air India flight AI171, a 787-8 on departure from Ahmedabad, is the first hull-loss involving fatalities of the type and remains under formal AAIB India investigation with NTSB participation.
Type overview
The 787 entered service with All Nippon Airways in October 2011 after a three-year delay from the original 2008 target. Three production variants are in service:
- →787-8 — original variant, range up to ~13,500 km; ANA was launch customer
- →787-9 — stretched variant, range ~14,140 km; the largest-volume Dreamliner variant
- →787-10 — longest variant, range ~11,750 km; Singapore Airlines launch customer 2018
The aircraft uses approximately 50% composite materials by weight, including the fuselage. Powerplant choice is split between GE Aviation GEnx-1B and Rolls-Royce Trent 1000 (Rolls Trent 1000 TEN being the latest in-service variant).
Safety record — notable events
After two lithium-ion battery thermal-runaway events on JAL (Boston) and ANA (Takamatsu) aircraft, the FAA grounded the entire 787 fleet on 16 January 2013. EASA, JCAB, and other regulators followed. The fleet returned to service in April-May 2013 after Boeing redesigned the battery enclosure and venting system; NTSB and JTSB reports cited internal cell short-circuit propagation.
Boeing paused or slowed 787 deliveries for extended periods after non-conformances were found in fuselage joins and shim-gap tolerances on aircraft built at the Charleston facility. Around 122 stored aircraft underwent rework; Boeing announced in February 2025 that the rework programme for those aircraft had been completed.
A 787-9 operating Sydney-Auckland experienced a sudden uncommanded pitch movement during cruise; multiple occupants were injured. NZ TAIC investigation, with Chilean DGAC and US NTSB participation, examined cockpit-seat actuation hardware as a contributing area.
In April 2024, Boeing engineer Sam Salehpour publicly raised concerns about fuselage-join quality on the 787. The FAA opened a review of the allegations. Boeing rejected the broader structural-fatigue claim and provided technical data; the FAA review continued through 2024-2025.
Italian authorities opened a probe into Manufacturing Process Specification (MPS), a supplier whose components had reportedly been used on the 787, alleging falsified material certifications for over 4,800 parts. Boeing initiated a parts-traceability review.
A 787-8 operating Ahmedabad (AMD) to London Gatwick (LGW) lost altitude shortly after rotation and impacted ground in the airport vicinity. Investigation is led by the Indian AAIB with participation by NTSB, UK AAIB, and the type and engine certifying authorities, as standard under ICAO Annex 13. As of the date of this profile, the formal investigation is ongoing; published preliminary information is the authoritative source. This is the first hull-loss involving fatalities of the 787 type.
Major operators
The 787 is the backbone of long-haul widebody fleets at most large intercontinental carriers. Representative operators (non-exhaustive):
| Operator | Region | Notable |
|---|---|---|
| All Nippon Airways (ANA) | Japan | Launch customer; -8, -9, -10 mix |
| United Airlines | USA | Large -8/-9/-10 long-haul fleet |
| American Airlines | USA | -8 and -9 widebody backbone |
| Qatar Airways | Qatar | -8 and -9 in service |
| British Airways | UK | -8, -9, -10 long-haul |
| Etihad, Saudia, EVA Air, KLM | Multi-region | Various variant mixes |
| Air India | India | -8 fleet; operator of AI171 |
| Singapore Airlines | Singapore | -10 launch customer 2018 |
Certification status and recent ADs
- →Lithium-ion battery containment (2013, residual): the redesigned battery enclosure remains the certification standard for in-service 787s.
- →FAA AD on power-cycle counter (2020): mandates power-cycle resets at defined intervals to prevent stale flight-control data, addressing a software issue identified in service.
- →Rolls-Royce Trent 1000 inspection ADs (multiple, 2018-2024): EASA and FAA mandates on inspection intervals for compressor blade durability on early Trent 1000 (Pack B, Pack C) engines. Trent 1000 TEN is the current production variant.
- →Production-quality oversight: FAA has maintained enhanced production-quality oversight at Boeing 787 facilities since the 2020-2022 rework period; the level of oversight increased again post-AS1282 across all Boeing programmes.
- →AI171 — investigation outputs pending: any certification action arising from the Ahmedabad accident will follow ICAO Annex 13 procedure and be published by the Indian AAIB and the type certifying authority.
Recent 2024-2026 operational notes
The 787 remains the most widely operated long-haul widebody by deliveries through 2026, with deliveries averaging in the dozens per year as Boeing restored its post-2022 production cadence. The aircraft is ETOPS 330-minute approved, enabling the longest commercial overwater routings in service (used for Pacific and South Atlantic operations). The June 2025 AI171 event is the only fatal hull-loss event in the type's operational history; the operational fleet continued normal service worldwide throughout the investigation period under the type certifying authority's ongoing review.
