FAA Proposes Replacing Sensors on Pratt & Whitney Jet Engines

The Federal Aviation Administration has proposed a new rule requiring airlines and maintenance shops to replace specific pressure burner sensors in certain Pratt & Whitney jet engines. This is an airworthiness directive, which means it would become mandatory if finalized.

Why it matters: This action addresses a specific mechanical failure that can cause serious safety issues mid-flight. While the number of affected engines is relatively small, the risk involves potential fire or loss of control, which justifies mandatory maintenance rather than voluntary repair.

Who it affects

• Airlines and operators using Pratt & Whitney PW4052, PW4056, PW4060, PW4060A, PW4060C, PW4062, PW4062A, PW4152, PW4156, PW4156A, PW4158, PW4460, and PW4462 engines.
