Aerial Application Flight Ends in Overrun and Tail Damage (N731ED)

Opheim, MT, US

On June 29, 1996, a Cessna A188B (registration N731ED) was involved in an aviation accident near Opheim, MT. Investigators recorded the probable cause as: the pilot's failure to follow the proper short field takeoff procedure as specified in the Airplane Flight Manual, his improper use of wing flaps during the takeoff, and his failure to abort the takeoff (while there was sufficient runway remainin). This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An agricultural flight aborted a takeoff, then attempted a second takeoff with full flaps, resulting in a bounce, overrun, and tail section damage. The flaps were found at 20 degrees, exceeding the manual's 10-degree limit for short field takeoffs. The operator lacked a valid agriculture operating certificate.

Accident Details

The pilot loaded the airplane with herbicide and fuel for a local aerial application flight. The takeoff was initiated northbound on a 2,675-foot grass airstrip. Light winds were from the southwest. After traversing approximately two-thirds of the runway without becoming airborne, the pilot elected to abort the takeoff.

Pilot Actions

The pilot then began another takeoff to the south from the opposite end of the runway. He selected full flaps for this takeoff. After traversing half of the runway, the airplane's tail came up, and the airplane began to bounce up and down along the remaining runway length. The airplane overran the runway and impacted a berm, resulting in substantial damage to the tail section.

Investigation Findings

At the accident site, the flaps were found in the fully extended position, which is 20 degrees. According to the airplane flight manual, flaps should not be placed beyond the 10-degree position for a short field takeoff. Additionally, the inspector stated that the operator did not hold a valid agriculture operating certificate at the time of the accident.
