## The airworthiness directive

50-01-01 MOONEY: Applies to All Model M-18L Aircraft. Compliance required as soon as possible but not later than next 25 hours operating time and at each 25-hour period thereafter until reinforcement of engine mount lugs is accomplished. Inspect the four engine mount lugs for cracks. If cracks are evident, reweld the lugs to mate with the mount holes on the engine and weld an X-4130 0.058-inch strap 1/2 x 3-inches to the lug and the side tube member. Further inspections are not necessary after the above reinforcement of the lugs is made. (Mooney Service Bulletin No. 4 covers this same subject.)
