The FAA has proposed a new airworthiness directive that supersedes AD 2026-09-02 for certain Pratt & Whitney RTX Corporation engines, mandating repetitive angle ultrasonic scan inspections of HPC 15th‑stage disks, front turbine hubs, HPT 1st‑stage air seals, and HPT 2nd‑stage hubs for crack indications and removal if necessary.
The agency also adopted an airworthiness directive for Pratt & Whitney Division engines, including models PW4052, PW4056, PW4060, PW4060A, PW4060C, PW4062, PW4062A, PW4152, PW4156, PW4156A, PW4158, PW4460 and PW4462, requiring replacement of pressure burner sensors after reports of tailpipe fire, loss of thrust control and in‑flight engine shutdown.
