EASA AD US-2024-06-03
Electrical Power - P6 Panel / Standby Power Control Unit - Installation
Summary
Airworthiness Directive 2024-06-03 is a final rule issued by the Federal Aviation Administration (FAA) addressing certain Boeing 737-8 and 737-9 airplanes. It mandates the installation of two bonding jumpers from the P6 panel structure to the primary structure to prevent failure of the standby power control unit (SPCU). This directive aims to maintain critical flightcrew instrumentation and displays by ensuring redundant grounding paths.
What Changed
This new airworthiness directive introduces a requirement to install two bonding jumpers to provide redundant ground paths for the SPCU on Boeing 737-8 and 737-9 models. It addresses a single point of failure condition that could cause loss of SPCU function and other P6 panel functions. The directive does not amend or supersede any previous ADs but establishes a new compliance mandate.
Why It Matters
This directive is critical for aviation professionals as it prevents potential loss of essential flightcrew instruments and displays caused by SPCU failure. Operators and maintenance teams must ensure the electrical bonding is compliant to avoid unsafe conditions that could compromise safe flight and landing. Compliance ensures continued airworthiness and operational safety of affected Boeing 737 aircraft.
What To Do
Operators of Boeing 737-8 and 737-9 airplanes must install the two bonding jumpers as specified in Boeing Alert Requirements Bulletin 737-24A1248 RB dated May 16, 2022. The installation must be completed by May 22, 2024, the effective date of the AD. Any alternative methods of compliance require FAA approval prior to implementation.
