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.
