## The airworthiness directive

51-11-02 CESSNA: Applies to All Models 190 and 195 Aircraft Serial Numbers 7004 to 7474 and 7476 to 7479, Inclusive.

Compliance required not later than June 1, 1951, and upon each 100 hours of operation thereafter until reinforcing doublers are installed at outboard hinge fittings.

Inspect for fatigue cracks in the elevator spar webs at the outboard hinges. This may be accomplished by loosening the two attaching bolts as necessary to facilitate inspection for cracks at the bolt holes. Cracks extending less than 3/4 inch beyond the hinge fitting should be stop- drilled and reinforcing doublers, Cessna P/N 10008-11-2 and -3, should be installed on the forward side of the spar. If any cracks are longer than 3/4 inch, the spar should be replaced and the reinforcing doublers added.

(Cessna Service Letter No. 10 dated November 18, 1949, covers this same subject.)
