AD: The Boeing Company Airplanes

AD 2022-15-07 Requires Revising The Existing Airplane Flight Manual (AFM)

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 series airplanes.

This AD was prompted by a report that after a certain circuit breaker tripped, power to the two pitot-static (P/S) probe heaters on the right-hand side was lost, and the flightcrew discovered conflicting procedures in the flightcrew operations manual/quick reference handbook (FCOM/QRH). This AD requires revising the existing airplane flight manual (AFM) to incorporate procedures to be applied during P/S probe heater failure conditions. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective September 15, 2022. 

Supplementary Information: The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 747-400 series airplanes. The NPRM published in the Federal Register on December 28, 2021 (86 FR 73694). The NPRM was prompted by a report that after a certain circuit breaker tripped, power to the two P/S probe heaters on the righthand side was lost, and the flightcrew discovered conflicting procedures in the FCOM/QRH. In the NPRM, the FAA proposed to require revising the existing AFM to incorporate procedures to be applied during P/S probe heater failure conditions. The FAA is issuing this AD to address the conflicting procedures, which could result in the transmission of potentially inaccurate pitot static pressure data to the air data computer (ADC), resulting in erroneous or misleading air data being displayed, which, in combination with a stall, overspeed, overrun, or short/hard landing condition, could result in reduced ability of the flightcrew to maintain continued safe flight and landing of the airplane.
