Loss of Control

LOCWGLoss of control is on NTSB’s 2016 “Most Wanted List” of advocacy priorities. FAA explains loss of control as an unintended departure of an aircraft from controlled flight.

The GAJSC conducted a detailed review of 180 fatal general aviation accidents that occurred between 2001 and 2010 and were identified as “loss of control,” according to CICTT taxonomy.

The work was performed by two work groups: Loss of Control Work Group 1 (LOCWG1), focused on fatal general aviation accidents that occurred during approach or landing, and Loss of Control Work Group 2 (LOCWG2), which conducted analysis of fatal general aviation accidents that occurred during other phases of flight.

LOCWG1, tasked with analyzing accidents that occurred during the approach and landing phases of flight, was comprised of three sub teams, based on accident selection subsets of experimental amateur-built, certified piston engine airplanes, and turbine engine powered airplanes. NTSB data from sixty randomly selected accidents were given to each sub group; the first thirty well-documented accidents from each were analyzed in detail. Based on the analyses, the group developed Safety Enhancements.

LOCWG1In 2012, LOCWG1 issued its report to the GAJSC for review and approval. The Safety Enhancements recommended in this report are listed below, with links to relevant output resources.

LOCWG2 focused on analyzing accidents that occurred during the departure and en route phases of flight. NTSB data from 120 sixty randomly selected LOC accidents was given to LOCWG2 for analysis; the first ninety well-documented accidents were analyzed in detail for the development of Safety Enhancements.

In 2014, LOCWG2 issued its report to the GAJSC for LOCWG1review and approval, combined with recommendations from LOCWG1. The new Safety Enhancements recommended in this report are listed below, with links to relevant output resources.

A list of combined recommendations from LOCWG1 and LOCWG 2 follow.
