Take, for example, the tragic crashes of two Boeing 737 MAX aircraft a few months apart in 2018 and 2019. A key aviation engineering principle is that safety-critical systems cannot have a single ...
Examples of debris on a runway or aircraft carrier flight deck that can cause damage are pieces of tire rubber, litter and nuts and bolts. A specific example is a metal piece dropped from another plane. [3] Runways and aircraft carrier flight decks are cleaned frequently in an attempt to preclude ingestion of foreign objects.
Boeing's 737 MAX 7 and 10 are delayed as the planemaker works to address an engine anti-ice system that could lead to it overheating and potentially causing an engine failure before the planes can ...
Manufacturers often underestimate the cost of the D check. Boeing underestimates the cost for four of its aircraft, and the expectation is that it has underestimated it for the B787-9 which in 2018 had not been in service for long enough to have been put through a D check. [15] All amounts in millions of United States dollars, as of 2018. [15]
For the Airbus A320neo and Boeing 737 MAX, between 52% and 57% of their value lies in their engines: this could rise to 80–90% after ten years, while new Airbus A350 or Boeing 787 engines are worth 36–40% of the aircraft. After some time the maintenance reserves exceed the aircraft lease. [31]
Federal Aviation Administration chief Mike Whitaker said the plan is comprehensive and includes encouraging Boeing employees to speak up about safety concerns. “This is a guide for a new way for ...
Because the CFM International LEAP engine used on the 737 MAX was larger and mounted further forward from the wing and higher off the ground than on previous generations of the 737, Boeing discovered that the aircraft had a tendency to push the nose up when operating in a specific portion of the flight envelope (flaps up, high angle of attack ...
In light of the engine fire, the UK aviation safety agency has asked the Federal Aviation Administration (FAA) in the US to take action against Boeing to improve the safety of the 767 fleet.
