5-40. CRACKED CABIN WINDOW.
If crack(s) in cabin window ply(s) occurs in-flight,
perform the Cracked Cabin Window emergency
procedure in Chapter 9. If a cabin window has
developed a crack, the aircraft shall not be flown, once
landed, without proper ferry flight authorization.
If cracking, chipping, or stress crazing that can
be felt with the fingernail occurs in either ply of the
cabin window, the window should be replaced in
If, for some reason, the window cannot be
replaced prior to the next flight, unpressurized flight
may be conducted, provided the following placards are
installed in the aircraft.
The following placard must be placed in clear
view of the pilot:
PRESSURIZED FLIGHT IS PROHIBITED
PRESS SWITCH IN THE DUMP POSITION.
The following placard must be placed next to the
If a crack is found in both the inner and outer
plies of the cabin window, the window must be

5-41. INTENTIONAL ENGINE OUT SPEED.
Intentional in-flight engine cuts below the safe
one engine inoperative speed (Vsse, 104 KIAS) are
5-42. LANDING ON UNPREPARED RUNWAY.
Except in an emergency, propellers should
be moved out of reverse below 40 knots to
minimize propeller blade erosion, 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
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. When landing on
other than dry surfaces, use discretionary propeller
reverse to stop the aircraft on the available runway.
Section IX. REQUIRED EQUIPMENT FOR VARIOUS CONDITIONS OF FLIGHT
5-43. REQUIRED EQUIPMENT LISTING.
The Required Equipment List (REL) is approved
by the Directorate of Evaluation and Standardization
(DES) USAAVNC, Fort Rucker. It is fully coordinated
with the Master Minimum Equipment List (MMEL) and
AR 95-1. It is the governing document for flight with
inoperative components and items of equipment.
Changes or modification to the REL are not authorized
unless approved by DES and distributed by the Fixed
Wing Product Managers Office (FWPMO).
