This bulletin is not mandatory but serves to inform operators and maintainers of the safety concern.
What Changed
This bulletin introduces awareness of possible skin corrosion under the dorsal oxygen line fairing on Learjet Model 60 aircraft, a condition not previously covered by maintenance inspections. It recommends inspections per Learjet Service Bulletin 60-53-19 and notes that the FAA may issue an Airworthiness Directive on this matter, which EASA would likely adopt.
Why It Matters
The potential for undetected skin corrosion under the oxygen line fairing could affect the structural integrity of affected Learjet Model 60 aircraft. Aviation professionals, including operators and maintenance organizations, need to be aware of this issue to prevent possible safety risks and to prepare for forthcoming regulatory requirements. Early detection and corrective actions can help maintain airworthiness and compliance.
What To Do
Operators and maintenance personnel of Learjet Model 60 aircraft should perform inspections as outlined in Learjet Service Bulletin 60-53-19 and carry out any necessary corrective actions if corrosion is found. Findings should be reported to Learjet using the contact information provided. There is no mandatory compliance deadline as this bulletin is informational only, pending potential FAA AD issuance.
