FAA orders inspections of nearly 2,000 Boeing 737 aircraft
The FAA ordered inspections of 1,987 Boeing 737 Next Generation aircraft in the US due to pitch oscillation risks from excessive free play in the horizontal stabilizer mechanism. The directive, effective November 23, 2026, requires measuring free play and potential repairs. The FAA rejected airlines' requests to extend deadlines, citing safety concerns. The total cost for inspections is estimated at $1 million, excluding repairs.
