## The airworthiness directive

57-10-01 MOONEY: Applies to Model M-20 Aircraft Serial Numbers 1002 Through 1126 Incorporating Main Landing Gear Retracting Bellcrank Bracket P/N 5035. To be accomplished as soon as practicable but not later than July 1, 1957. Cracks have been reported in the main landing gear retracting bellcrank bracket P/N 5035. In one case complete failure of the bracket resulted in jamming the elevator control system. Therefore, it is required that bracket PN 5035 be replaced by new redesigned brackets P/N 5101 which have a 0.095 inch wall tubing. The revised retracting bellcrank bracket P/N 5101 incorporated a reinforcing angle at the lower front corner and a cross member between the gear bungee fittings. (Mooney Service Letter 20-22 covers this same subject.)
