Fuel Planning Errors in General Aviation from 2015 to 2020

Abstract

BACKGROUND: Planning, whether preflight or in-flight, is a cause of accident that is presumably almost entirely preventable. Planning skills on the part of the pilot should assist in avoiding dangerous situations with regards to light conditions, weather, fuel shortage, and/or improper weight and balance. Fuel planning is noted as especially unnecessary, as fuel planning is not considered a complex skill but part of proper flight preparation and in-flight planning.METHODS: A total of 196 accident reports from 2015 until 2020 were extracted from the NTSB online database in which the probable cause included either preflight or in-flight planning as a cause attributed to the pilot. Of those accidents, the majority (N = 131, 67%) were attributed to fuel planning and were further analyzed.RESULTS: Fuel-planning related accidents were significantly less often fatal compared to all planning-related accidents and all fuel-related accidents. The majority of fuel planning accidents resulted in fuel exhaustion. Additionally, the cause attributed to the accidents was frequently the skill-based error of “fuel planning (pilot)” and the crew resource management issue of “fuel-fluid level”. Specific information regarding the pilot’s fuel plan was only available in 52 (40%) of the accident reports.CONCLUSIONS: The frequency of fuel-related planning accidents suggests that this aspect of pilotage is underestimated and requires more attention both in training and in standard operating procedures. In particular, more detailed information regarding the pilot’s fuel plan is necessary in order to determine which step in the process most frequently results in an accident.Kalagher H.
