EASA SIB CE-18-22
Alternative Method of Compliance to FAA AD 2018-06-11
Summary
The Special Airworthiness Information Bulletin titled Alternative Method of Compliance to FAA AD 2018-06-11 is an informational document regarding an approved alternative method of compliance for Textron Aviation Inc. Models A36TC, B36TC, S35, V35, V35A, and V35B airplanes. It addresses the life limit and inspection requirements for the exhaust tailpipe v-band coupling specified in FAA Airworthiness Directive 2018-06-11.
What Changed
This bulletin announces the availability of a global alternative method of compliance that allows the use of the standard specification part number S1921-1 as a substitute for three of the Textron Aviation part numbers required by FAA AD 2018-06-11. This alternative is intended to alleviate parts availability issues and does not apply to airplanes equipped with STC SA1035WE.
Why It Matters
This alternative method of compliance is important because it helps operators avoid grounding their aircraft due to shortages of specific exhaust tailpipe v-band coupling parts mandated by FAA AD 2018-06-11. It provides a practical solution to maintain compliance while ensuring continued airworthiness and operational readiness of affected Textron Aviation models.
What To Do
Operators and maintenance personnel should review the global AMOC dated July 11, 2018, attached to this bulletin, to determine eligibility for using the S1921-1 part number as an alternative. They should ensure that the alternative part is used only where permitted and confirm that their aircraft are not equipped with STC SA1035WE.
