On March 25, 1989, a Bellanca 7KCAB (registration N90985) operated by Aerial Messages, Inc. was involved in an aviation accident near Daytona Bch Shr, FL. Investigators recorded the probable cause as: IN-FLIGHT LOSS OF CONTROL WHILE MANEUVERING TO REVERSE DIRECTION DUE THE FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED DURING THE 'STEEP TURN.'. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A Bellanca banner-towing aircraft struck a wave and nosed into the water after executing a tight turn offshore. Examination found no evidence of failure in flight controls, engine, or banner release mechanism.
Accident Description
A Bellanca aircraft engaged in banner towing was flying southbound offshore at an altitude of 300–400 feet. The aircraft passed to the right of the last aircraft in a flight of four Super Cub banner-towing aircraft, which were cruising at about 40 mph. This maneuver placed the Bellanca closer to shore. With a quartering tailwind, the pilot initiated a “very tight” right turn to return northbound. During the turn, the aircraft performed what was described as a “wing over” and began descending eastbound with the banner still attached. As it descended, the main landing gear contacted a wave, causing the aircraft to nose into the water.
Aircraft Examination
Post-accident examination of the aircraft and engine revealed no evidence of failure or malfunction of the flight controls or the engine. The banner release mechanism was also examined and showed no evidence of failure or malfunction.
Additional Information
The minimum altitude for banner towing operations, other than for pickups and drops, is 500 feet when authorized by ATC. The aircraft was operating at 300–400 feet at the time of the event.
