A FACTOR RELATED TO THE ACCIDENT WAS: LACK OF COORDINATION BETWEEN THE PILOT AND GROUND PERSONNEL TO INFORM THE PILOT OF THE EXTRA LENGTH OF THE TOW LINE. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, maneuvering - towing/advertising/external load equipment - undetermined (cause) - In flight collision with terrain/water, maneuvering - crew/group coordination - inadequate (contributing factor) - load jettison - not possible - climb - not possible - terrain condition - water - stall/mush ## Analysis THIS WAS THE PILOT'S THIRD BANNER TOW FLIGHT OF THE DAY. THE FIRST AND SECOND BANNER DROPS WERE SUCCESSFUL. ON THE THIRD DROP, THE PILOT WAS UNABLE TO RELEASE THE BANNER AND IT DRAGGED ON THE GROUND, THEN INTO THE WATER OF A NEARBY BAY. THE PILOT REPORTED THAT WHEN THE BANNER WENT INTO THE WATER, THE RESULTANT DRAG WAS TOO MUCH FOR THE AIRCRAFT TO OVERCOME. HE WAS UNABLE TO SUSTAIN FLIGHT, AND THE AIRPLANE CONTACTED THE WATER. THE PILOT STATED THAT UNKNOWN TO HIM, THE THIRD TOW LINE WAS 50 TO 75 FEET LONGER THAN THE OTHERS. DURING AN INVESTIGATION, THE TOW RELEASE MECHANISM WAS ACTUATED SIX TIMES (WITHOUT A LOAD), AND IT FUNCTIONED PROPERLY. ## Factual narrative On Sunday, August 15, 1993, at 1230 eastern daylight time, a Cessna 305A, N53136, operated by Aerial Advertising, Inc., and piloted by David L. Coleman, sustained substantial damage, when it impacted the water near Beach Haven, New Jersey. The pilot received minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed. The flight was being conducted under 14 CFR 91. This was the third banner tow flight of the day for this pilot. The two earlier banners were picked up; towed; and dropped without incident. In his report, the pilot stated: The third banner, unknown to me, was on a tow line which was 50' to 75' longer than the previous tow lines. At the drop area, I was watching the ground crew for a signal to release the banner. As the A/C [aircraft] [approached] what I felt [was] too far past the [drop area], I pulled the release handle, but the banner did not drop. Almost immediately, the banner could be felt dragging the ground. I added power to climb and tried again to release the banner. By this time the banner was in the water. The weight of the banner in the water was too much for the A/C to overcome....even with power the A/C entered the water... Mr. David J. Grasso, Aviation Safety Inspector for the Federal Aviation Administration, examined the wreckage. In his report, Mr. Grasso stated: ...I arrived to check the banner release after the aircraft was removed from the water. The release was actuated 6 times (without a load applied) and it operated correctly. ## Aircraft - Registration: N53136 (not matched to a registry record) - Reported make and model: CESSNA 305A - Category: Airplane - Serial number: 23428 - Engines: CONTINENTAL O-470-11B 210 horsepower reciprocating - Damage: Substantial damage - Flight: Part 91 - Operator: Aerial Advertising, Inc. - Registered owner: Airway Advertising, Inc. - Airworthiness certificate: Standard, Normal - Departed: 47N, MANVILLE, NJ - Destination: 47N - Airport: N44, R.J.

Banner release failed. Banner dragged in water forced aircraft down. Ground crew failed inform extra length towline From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
