1 General

This section describes the procedures necessary to safely and efficiently operate your aircraft. A basic understanding of helicopter flight techniques is assumed. Some of the items on the checklist are intended to be performed by the flight engineer. These items are marked with an (F).

2 Preflight Procedures

2.1 Exterior Checks

  1. Main Rotors - check condition
  2. Forward Pylon - check as follows (open access panel)
    1. Forward transmission - check condition
    2. Forward transmission oil level - check sight gauge
    3. #1 Flight Control Hydraulics - check condition
  3. Aft Pylon - check as follows (access on front of plyon)
    1. Combining transmission - check condition
    2. Engine #1 transmission - check condition
    3. Engine #2 transmission - check condition
    4. Combining transmission oil level - check sight gauge
    5. Engine #1 transmission oil level - check sight gauge
    6. Engine #2 transmission oil level - check sight gauge
  4. Engine #1 - check as follows (open access panel)
    1. Engine - check condition
    2. Engine Oil Level - check indicating bar near top
  5. Engine #2 - check as follows (open access panel)
    1. Engine - check condition
    2. Engine Oil Level - check indicating bar near top

2.2 Interior Checks

  1. Ramp Overhead Area Checks
    1. APU - check condition
    2. APU Generator - check condition
    3. Aft transmission - check condition
    4. #1 Generator - check condition
    5. #2 Generator - check condition
    6. #1 Flight Control Hydraulic Pump - check condition
    7. Utility Hydraulic Pump - check condition
    8. Aft transmission oil level - check sight gauge
    9. Engine Fire Agent Bottles - check condition and pressure. 500 psi minimum.
  2. BATT switch - ON
  3. Check fuel levels
  4. Check aft maintenance panel as follows
    1. Hydrualic fluid levels - check Utility, FC #1 and FC #2
    2. Ground contact lights - check L & R ON
    3. Oil pressure warning lights - check ON
    4. Ground Test Switch - ON
    5. All maintenace panel lights - check ON
    6. Ground Test Switch - OFF
  5. BATT switch - OFF
