Investigation Summary
The Boeing 777-200ER was climbing through 7,000 feet when the right engine surged. The crew declared an emergency and requested an immediate return to LAX. When specifically asked by Air Traffic Control if they needed to dump fuel to reduce weight, the crew replied 'Negative.' However, due to the aircraft being heavy for a transpacific flight, the pilots subsequently elected to jettison fuel to mitigate the risk of a structural failure or runway overrun. This decision was made without notifying ATC, contradicting their earlier statement. The fuel was dumped at approximately 2,000 feet while the aircraft was on the final approach path. Because of the low altitude, the fuel did not atomize completely before reaching the ground, coating several elementary school playgrounds in liquid jet fuel.
Final Conclusions
The FAA investigation concluded that while the emergency justified a return to the airport, the crew failed to follow standard operating procedures which dictate that fuel dumping should occur over unpopulated areas or at higher altitudes to allow for evaporation. The crew also failed to notify Air Traffic Control that they intended to dump fuel, which prevented ATC from providing vectors to a safer location.

Systems & Failure Modes
Fuel Jettison System
A system designed to reduce aircraft weight in emergencies by pumping fuel out of nozzles on the wingtips.
Trent 892 Engine
The Rolls-Royce powerplants; the right engine suffered a compressor stall shortly after departure.
Interesting Facts
- 01The aircraft dumped approximately 15,000 gallons of Jet A fuel.
- 02At least 56 people on the ground, mostly children, were treated for skin and lung irritation.
- 03The fuel was dumped at an altitude of roughly 2,300 feet AGL.
- 04Boeing 777 manuals state fuel dumping should ideally occur above 5,000 feet to ensure evaporation.
- 05The aircraft landed 13,000 lbs over its maximum structural landing weight.
- 06In 2024, Delta Air Lines reached a $78.75 million class-action settlement to resolve claims from affected residents and schools.
Safety Actions & Advisories
Pilot Training Revision
Delta Air Lines updated its emergency checklists and simulator training to emphasize ATC communication during fuel jettison events.
FAA Enforcement
The FAA initiated an investigation into the crew's deviation from standard operating procedures regarding low-altitude fuel dumping.
