EASA AD US-2024-10-15
Powerplant - Engine Mounts - Inspection / Repair / Revision of Aircraft Maintenance Manual
Summary
The Federal Aviation Administration's Airworthiness Directive 2024-10-15 addresses certain Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. This directive mandates inspection and repair of engine mount hardware due to a reported failure of a rear engine mount that caused visible engine misalignment. It also requires revising the aircraft maintenance manual to update procedures for engine removal and installation.
What Changed
This new airworthiness directive introduces mandatory inspections of left and right engine mount points for non-conforming hardware installations and requires repairs if necessary. It also mandates revisions to the existing aircraft maintenance manuals to correct and clarify engine removal and installation procedures. The compliance time for inspections is set within 30 days of the directive's effective date, accelerating previous recommendations.
Why It Matters
This directive is critical for aviation professionals because failure of an engine mount can lead to engine separation and loss of airplane control, posing significant safety risks. Operators and maintenance organizations must ensure compliance to prevent potential accidents and maintain airworthiness. The updated maintenance manual procedures help reduce errors during engine installation and improve overall maintenance quality.
What To Do
Affected operators must inspect engine mount hardware on Gulfstream GVII-G500 and GVII-G600 airplanes within 30 days of June 7, 2024, and repair any non-conforming installations before further flight. They must also revise their aircraft maintenance manuals to incorporate the updated engine removal and installation procedures as specified. Comments on the directive can be submitted to the FAA by July 22, 2024.
