TRIM AND RIGGING - TM-1-1510-223-MTF0128

TM 1-1510-223-MTF

23. Right ENVIRO & PNEU BLEED AIR switch - PNEU ONLY.

24. Slowly retard the left POWER lever to flight idle and determine the

minimum N. required to maintain cabin pressure. Verify that cabin

pressurization is maintained down to flight idle N1.

25. Right ENVIRO & PNEU BLEED AIR switch - ON.

26. Cabin pressurization controller - Set to 500 feet above field

elevation.

* B. TRIM AND RIGGING

Check as follows:

In smooth air, at cruise power, the aircraft will fly hands off, straight

and level with the ailerons symmetrically aligned at the trailing edge

and the aileron adjustable tab set to zero.

* C. MAXIMUM TGT/N1 AVAILABILITY

Ensure that sufficient POWER lever travel is available at 16,000 feet

to produce a TGT of 840 or an N. of 104%. Check the maximum

POWER lever position as follows:

NOTE

The only requirement of the maximum POWER lever

position check is to verify that it is possible to obtain

maximum allowable gas generator RPM (No) with the

POWER levers in the full forward position. If during the test

the TGT temperature limit or N1 limit is obtained prior to

reaching maximum N1, the check is completed.

Altitude - 16,000 feet pressure altitude.

PROP levers - Set 1700 RPM.

Ice vanes - Retracted.

ENVIRO & PNEU BLEED AIR valve switches (2) - ON.

Airspeed - As required.
