The airworthiness directive
48-32-01 TIMM: Applies to Models N2T All Serial Numbers, and PT-220-C Aircraft.
Compliance required as indicated.
Instances have been reported of throttle quadrants pulling off the fuselage skin to which they were glued and nailed during manufacture. Both front and rear cockpit throttle quadrants must therefore be inspected for looseness immediately and if found loose must be repaired prior to the next flight.
This inspection should be repeated frequently until such time as the throttles are reinforced as described below, or in an equivalent manner. Reinforcements must be installed not later than January 1, 1949.
1. Insert four AN 3 bolts through wood plate on outboard side of throttle quadrants through support blocks and fuselage skin using one bolt at each plate corner. Install large flat washers or metal backing plates beneath bolt heads and nuts to avoid crushing wood. Loose throttle quadrants should be reglued prior to making this reinforcement.
