## The airworthiness directive

76-05-09 AER PEGASO (AEROMERE & AVIONAUTICA RIO): Amendment 39-2544. Applies to M100S gliders, certificated in all categories.

Compliance is required within the next 50 hours time in service after the effective date of this AD, unless already accomplished.

To prevent separation of lower rudder hinge pin from the rudder hinge bracket and the consequent loss of rudder control, accomplish the following:

Replace the lower rudder hinge pin with a new pin made of SAE 1024 steel and inspect the new pin's weld for cracks, using the dye penetrant method, in accordance with the steps (1) through (9) of the Description section of Ingg. A. & P. Morrelli (Aer Pegaso) Technical Bulletin No. 11/M100S, dated March 16, 1971, or an FAA- approved equivalent.

This amendment becomes effective March 25, 1976.
