Note 1: FAA AD 96-10-03 Amdt 39-9608 refers.
Note 2: The Requirement instructions of this Directive do not mirror the instructions in Piper SB 965. This Directive requires installing the clevis bolt, regardless of the condition of the current part.
Compliance: Upon the accumulation of 2,000 hours time in service or within the next 100 hours time in service after 15 August 1996, whichever occurs later.
Background: The FAA received reports of worn flap handle attach bolts and elongated holes in the flap lever to cable mounting attach point. Failure of the flap handle attach bolt could cause a sudden retraction of the flaps, and result in loss of control.
