EASA SIB 2008-85: WITHDRAWN - REPLACED BY FAA AD 2009-10-08

What to do

Affected operators and maintenance teams should monitor regulatory updates from the FAA and EASA regarding inspection requirements for PW2037 engines. They should also review current maintenance programs and be ready to implement additional inspections of the 2nd stage turbine hubs once mandated. No immediate mandatory actions or deadlines are specified in this bulletin.

Summary

EASA Safety Information Bulletin SIB No. 2008-85 is an informational bulletin concerning Pratt & Whitney PW2037 engines, which are installed on Boeing 757 aircraft among others. It communicates safety recommendations issued by the U.S. National Transportation Safety Board (NTSB) following an uncontained engine failure investigation. The bulletin informs European aviation authorities and operators about potential upcoming inspection requirements for the 2nd stage turbine hubs of PW2037 engines.

What changed

This bulletin does not introduce mandatory requirements but highlights that the NTSB has recommended the Federal Aviation Administration (FAA) to mandate additional inspections of the 2nd stage turbine hubs on PW2037 engines. It signals that such inspections may soon become compulsory to address safety concerns identified after an incident on 6 August 2008.

Why it matters

The information is critical for aviation professionals because it alerts operators and maintenance organizations to a potential safety risk involving uncontained failures of PW2037 engines. Early awareness allows stakeholders to prepare for forthcoming inspection mandates, ensuring continued airworthiness and regulatory compliance.
