The FAA on April 9 proposed an airworthiness directive for inspections of all models of Boeing’s 777 jetliner. The directive is based on the agency’s discovery of five 777s of various models with missing rivet heads used to join the aircraft’s skin. This directive is the second to affect the 777 in less than two months. The previous one was issued following the explosion of a Pratt & Whitney Canada PW 4000 engine in February.
Boeing’s 777 Back in the News Over Maintenance Issue
Key Takeaways:
- The FAA has proposed an airworthiness directive for all Boeing 777 jetliners requiring inspections due to the discovery of missing rivet heads on the aircraft's sloping pressure deck web.
- This condition, caused by inadequate rivets for the structural environment, could lead to severe consequences including decompression, loss of hydraulic systems, runway departure, and compromised structural integrity.
- The directive could affect nearly 225 aircraft, with an estimated repair cost of $33,000 per aircraft, and is the second such directive for the 777 in less than two months.
