Adds Revised True Flight Aerospace Critical Service
Bulletin
The FAA has issued a Special Airworthiness Information
Bulletin (SAIB) for True Flight Aerospace (Grumman American) Model
AA-5 airplanes. The bulletin addresses an issue concerning
the horizontal stabilizer forward spar attachment and surrounding
structure in the aft fuselage area.
This SAIB revises SAIB CE-09-37 to add True Flight Aerospace
Critical Service Bulletin SB-192, dated August 20, 2009.
During a routine inspection, maintenance personnel found cracked
and deformed structure in the aft fuselage area including
horizontal stabilizer forward spar attachment structure, spar
support angles, and stiffeners. After the original issuance of this
SAIB on July 1, 2009, a second airplane was found to have damage in
this area which prompted True Flight Aerospace to issue Critical
Service Bulletin SB-192, dated August 20, 2009.
The FAA recommends that owners and maintenance personnel perform
detailed visual inspections of the horizontal stabilizer forward
spar attachment structure, and surrounding area, of the AA-5
airplanes in accordance with True Flight Aerospace Critical Service
Bulletin SB-192 at every annual/100 hour inspection, and after hard
landings, tail strikes, or any other notable impact or force in
tail area.

The FAA asks that, if cracks or deformations are found, that a
Malfunction or Defect Report be submitted on the FAA’s
website. At this time, the FAA says this airworthiness concern is
not an unsafe condition that would warrant AD action under Title 14
of the Code of Federal Aviation Regulations (14CFR) part 39.
