Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

DURING THE STEP TAXI THE FLIGHT ENCOUNTERED ROUGH WATER AND THE AIRPLANE NOSED OVER.

NTSB Probable Cause

THE PILOT IN COMMAND'S IMPROPER TAXI SPEED. A FACTOR IN THE ACCIDENT WAS THE ROUGH WATER.

Full Narrative

On July 2, 1993, at 1000 Alaska daylight time, a float equipped Maule M4 airplane, N9872M, registered to and operated by the pilot in command, nosed over while taxiing on Char Lake, approximately 20 miles southwest of Iliamna, Alaska. The private certificated pilot and one passenger, the sole occupants, were not injured and the airplane sustained substantial damage. The personal flight, operating under 14 CFR Part 91, last departed Port Alsworth and the destination was Char Lake. No flight plan was filed and visual meteorological conditions prevailed. During a telephone interview, the pilot in command told the NTSB investigator in charge that he was performing a downwind taxi when the left float tucked beneath the water causing the airplane to roll inverted.
