(c) Propellers with affected blades that are continued in service regardless of the number of hours service, shall not be operated continuously between 2,250 and 2,400 r.p.m. Aircraft with affected blades installed shall be so placarded within 5 hours' time in service after the effective date of this AD. The placard may be removed when the blades are replaced.

(d) Identification of propeller blade serial numbers shall be determined in accordance with McCauley Service Bulletin No. 53 dated March 4, 1963.

(e) Replacement of blades shall be made in accordance with instructions in McCauley Service Bulletin No. 53 dated March 4, 1963.
