B. CONCURRENT REQUIREMENTS None.
C. REASON
(1) HISTORY Instances have been reported of corrosion in the mass-balance weights of the elevators. The corrosion may lead to loss of mass or the detach of the mass-balance weights, resulting in a unbalanced elevator which, in conjunction with some flight conditions, could result in loss of control of the aircraft.
(2) OBJECTIVE To inspect the mass-balance weights of the elevators, ailerons and rudder for corrosion and fragmentation of the mass-balance weights and replace as necessary.
(3) EXPECTED BENEFITS To guarantee that the aircraft complies with the designed installation requirements.
(4) REVISION HISTORY
(a) Revision 01 – This revision is being issued to include additional instructions to make the inspection of the Elevator, Aileron and Rudder mass-balance easier using a videoscope, and include SN 50500181 in the SB effectivity.
(b) Revision 02 – This revision is being issued to include additional instructions in the Accomplishment instructions and figure 3.
(c) Revision 03 – This revision is being issued to revise the Compliance time and include additional instructions in the Accomplishment instructions (include criteria for adjustable massbalance and improve fixed mass-balance criteria).
D. DESCRIPTION
(1) PART I - ELEVATOR MASS BALANCE AND ATTACHMENT PARTS INSPECTION
