Overview

This document is a checklist for the Piper PA-30 Twin Comanche, designed to assist pilots in conducting preflight, in-flight, and post-flight procedures. It includes emergency procedures, normal operations, and performance data essential for safe flight operations. The checklist is structured to ensure that all critical steps are followed, enhancing safety and efficiency during flight operations. It covers various phases of flight, including engine start, taxiing, takeoff, climb, cruise, descent, and landing, along with emergency protocols for engine failure, fire, and electrical issues.

  • Maintain minimum airspeed of 105 MPH during engine failure in critical flight phases.
  • Use full open throttle during an engine fire on start procedure.
  • For emergency descent, maintain an airspeed of 150 MPH and a bank angle of 30° - 45°.
  • Check oil pressure after engine start and ensure it is within normal limits.
  • Perform a manual landing gear extension if necessary, following the specified procedures.

Emergencies & Abnormals

This section outlines procedures for handling emergencies such as engine failure during takeoff and in-flight, engine fires, and electrical failures. Key actions include maintaining directional control, identifying affected systems, and executing emergency descents. Specific airspeeds and configurations are provided for various scenarios.

Before Start

The before start checklist includes securing seatbelts, checking circuit breakers, setting the fuel selector to main tanks, and ensuring generators are on. Cowl flaps should be opened prior to engine start.

Engine Start

During engine start, the checklist specifies holding brakes, opening throttles slightly, and ensuring the mixture is set to idle cut-off before turning on the master switch and engaging the starter. Oil pressure must be checked after starting.

Before Takeoff

Before takeoff, pilots must ensure the transponder is set, fuel selectors are on main tanks, and trim and flaps are properly set. Cowl flaps should be opened, and a takeoff briefing should be completed.

Important Speeds

This section lists critical airspeeds for the Piper PA-30, including Vr (90-97 MPH), Vmc (90 MPH), Vx (90 MPH), Vy (112 MPH), and approach speed (120 MPH). These speeds are essential for safe operation during various flight phases.

Safety notes

  • Do not begin unfeathering/restart procedures if engine damage is suspected.
  • Avoid running the flap motor for more than two seconds at a time during flap failure procedures.
