Preflight and Post-Flight Inspections

Question 1

SOP Requirements

Answer 1

d. Crews shall pre-flight immediately following NATOPS/Mission Brief. If setting an alert, PICs shall coordinate with maintenance control for pre-flight times prior to NATOPS/Mission Brief.

Question 2

Preflight

Answer 2

The following procedures shall be conducted for all ground and preflight flight operations:
1. Prior to supplying power to any system, a thorough preflight of the affected areas shall be conducted.
2. If engaging an engine for any reason (motoring excluded), a thorough preflight inspection of the entire aircraft is required. This is regardless of the intent to engage the rotors due to the potential of rotor brake slippage.
3. If maintenance personnel open panels, climb on top of the aircraft, or conduct any maintenance action after the crew conducted preflight inspection, crews shall verify the affected area is free of FOD and/or tools prior to any change in the aircraft status.
The procedures listed above are required regardless of the crew’s intention to fly.

Question 3

Postflight

Answer 3

Aircraft Postflight inspection is performed immediately
after aircraft shut-down to inspect for visible damage that may have occurred during flight. Aircraft
Postflight Inspection is performed per T/M/S MRCs.

Question 4

Pilot Aircraft Servicing

Answer 4

XMSN OIL: Accurate readings are not possible until 30 minutes after shutdown. The hot scale is
used 30 minutes to 2 hours after shutdown. The cold scale is used 2 hours or longer after shutdown.

ENGINE OIL: When the oil level reaches the ADD mark,
approximately 2 quarts of oil is required. Wait at least 20 minutes after engine shutdown before checking the engine
oil level or servicing to prevent potential engine seal failure upon restarting engine.

HYD FLUID: When the indicator reaches the REFILL (red) point, two-thirds of a pint is required to return the indicator to the FULL (green) mark.

APU OIL: The APU oil level can only be accurately checked using the dipstick. Wait
1 hour after APU shutdown prior to checking APU oil level.

Question 5

Cross-Country DTA Procedures

Answer 5

d. When aircraft must be operated away from the local area without qualified maintenance
support for periods not exceeding 72 hours, the CO may authorize the pilot-in-command to conduct
applicable T/M/S NATOPS pilot inspections in lieu of Preflight, Daily, Turnaround and Postflight
inspections, certify servicing requirements are accomplished, and sign the Aircraft Inspection and
Acceptance Record (OPNAV 4790/141) (Figure 5-4) in the certification block. In these cases, the
Daily Inspection must be performed immediately prior to the commencement of the mission. The
expiration of the CO 72-hour authorization may occur during the return flight to home base (or to a
site with maintenance support), per NOTE 3 of Figure 5-2. On a case-by-case basis, Wings and
MAGs may authorize an additional 24 hours (maximum of 96 hours), due to operational necessity.
COs must request the authorization in writing (email, letter, memorandum, or naval message) citing
the specific BUNO, name and rank of the pilot in command, and a description of the mission with
justification of operational necessity. Type Wing or MAG authorization must be in writing. The
email reference, Date Time Group (DTG) of the message, or serial number of letter authorizing the
deviation must be cited in the Daily Inspection WO or in the Aircraft Inspection and Acceptance
Record (OPNAV 4790/141) completed prior to commencement of the mission.
