FAA Aircraft Certification Service SPECIAL AIRWORTHINESS INFORMATION BULLETIN SAIB: CE-09-50 SUBJ: Alternative Method of Compliance for AD 2008-15-06 Date: September 23, 2009 This is information only. Recommendations aren’t mandatory.

Introduction

This Special Airworthiness Information Bulletin (SAIB) advises you, owners and operators of an alternative method of compliance (AMOC) for AD 2008-15-06, paragraph (e)(3).

Background

The current type-certificate holder has provided procedures other than the procedures provided in Cessna Single Engine Service Bulletin, SEB07-2, Revision 2, to do the engine mount bracket inspections required by AD 2008-15-06 in paragraph (e)(3). The AMOC letter, with the new procedures, is provided on Docket No. FAA-2007-29240.

Recommendations

To facilitate the inspections of AD 2008-15-06 and at the option of an aircraft operator, one 0.5-inch diameter hole may be added on the fuselage skin aft of each of the four brackets that are to be inspected. These added holes would facilitate borescope inspection of the bracket and its engine mount attach hole for deformation and cracks.

Therefore, the procedures in the above-referenced AMOC letter are considered an acceptable method of compliance to AD 2008-15-06.
