TM 1-1510-262-10
SECTION VIII. OTHER LIMITATIONS
5-40. MAXIMUM DESIGN SINK RATE.
The maximum design landing sink rate is 500 feet per minute, with a normal lare initiated just prior to touchdown.
5-41. INTENTIONAL ENGINE OUT SPEED.
Intentional in-light engine cuts below the safe one engine inoperative speed (Vsse = 115 KIAS) are prohibited.
Except in an emergency, propellers should be moved out of reverse below 40 knots to minimize
propeller blade erosion, and during crosswind to minimize stress imposed on propellers, engines,
and airframe. Care must be exercised when reversing on runways with loose sand or dust on the
surface. Flying gravel will damage propeller blades and dust may impair the pilot s forward visibility
at low aircraft speeds.
5-42. LANDING ON UNPREPARED RUNWAY.
The aircraft has demonstrated landings on hard, smooth runways. Hard braking, i.e., skidding tires while operating
on other than smooth runways can result in damage to the landing gear. Operations from unimproved runways
(rocks, potholes, mud, and deteriorated surfaces) are prohibited. When landing on other than dry surfaces, use
discretionary propeller reverse to stop the aircraft on the available runway.
