Preflight checklist explained

In aviation, a preflight checklist is a list of tasks that should be performed by pilots and aircrew prior to takeoff. Its purpose is to improve flight safety by ensuring that no important tasks are forgotten. Failure to correctly conduct a preflight check using a checklist is a major contributing factor to aircraft accidents.[1]

History

According to researcher and writer Atul Gawande, the concept of a pre-flight checklist was first introduced by management and engineers at the Boeing Company following the 1935 crash of the prototype Boeing B-17 (then known as the Model 299) at Wright Field in Dayton, Ohio, killing both pilots.[2] Investigation found that the pilots had forgotten to disengage the crucial gust locks (devices which stop control surfaces moving in the wind while parked) prior to take-off. Life magazine published the resulting lengthy and detailed B-17 checklist in its 24 August 1942 issue.[3]

Crashes attributed to checklist failures

FAR 121

The FAA's Federal Aviation Regulations explicitly requires a checklist for Federal Aviation Regulations, Part 121 operators (scheduled air carriers):[9]

NTRL.ntis.gov . 1988. 4 May 2022 . En . The report describes an accident in which an emergency landing was made because of severe yawing and engine torque fluctuation during climbout. It reviews evidence indicating that the probable cause of the accident was breakdown of the flightcrew coordination, which resulted in their failure to comply with the Before Takeoff Checklist and advance the RPM levels to the high RPM position, and the flightcrew's failure to diagnose and remedy engine oscillations on initial climbout. Crew training and checklist design are discussed and a safety recommendation is made to the Federal Aviation Administration regarding criteria for the type size of the checklist. .
