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.

The pilot and a passenger were departing a remote mountain lake in a float equipped airplane. The lake was at an elevation of about 2,000 feet mean sea level. The pilot departed toward the west with a right quartering headwind. The departure path placed the airplane in the lee of a small mountain. After departure, the airplane would only climb to about 100 feet above the ground. Higher terrain and trees were in the departure path. The pilot lowered the nose of the airplane to gain airspeed and then pulled up over several trees. The right wing contacted a tree, the airplane descended into other trees. The pilot noted that the accident could have been prevented by taking two trips (or) by waiting for a more beneficial wind condition and departure route.

NTSB Probable Cause

the pilot's improper planning/decision. Related factors were: the terrain condition, unfavorable (lee-side) wind, and trees.

Full Narrative

On September 15, 1996, about 1600 Alaska daylight time, a float equipped Champion 7GCBC, N9033L, crashed during takeoff from a remote area lake about 44 miles west of Skwentna, Alaska. The airplane was being operated as a visual flight rules (VFR) cross-country personal flight when the accident occurred. The airplane, registered to and operated by the pilot, sustained substantial damage. The certificated commercial pilot and the sole passenger were not injured. Visual meteorological conditions prevailed. On September 17, 1996, the pilot reported in a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) that he was departing Puntilla Lake located in the Alaska Mountain Range. The lake is located at an elevation of 2,000 feet mean sea level. During the takeoff toward the west, the pilot indicated a right quartering headwind of 10 knots with gusts to 15 knots, was present in the area. The departure path placed the airplane in the lee of a small mountain. After departure, the airplane would only climb to about 100 feet above the ground. The pilot indicated that higher terrain and trees were in the departure path. He lowered the nose of the airplane to increase the airspeed to about 75 MPH. He then pulled the nose of the airplane back and cleared several trees but the airspeed began to decrease. The right wing then contacted a tree and the airplane descended into numerous other trees. The airplane received damage to the floats, wings and fuselage. The pilot included a safety recommendation in the pilot/operator report submitted to the NTSB. The pilot noted the accident could have been prevented by..." making two trips, wait for more beneficial wind condition and departure route."
