A factor associated with the accident was sunglare. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Midair collision, cruise - light condition - sunglare (contributing factor) - visual lookout - inadequate, pilot in command (cause) - visual lookout - inadequate, pilot of other aircraft (cause) - Midair collision, cruise - light condition - sunglare (contributing factor) - visual lookout - inadequate, pilot in command (cause) - visual lookout - inadequate, pilot of other aircraft (cause) ## Analysis (aircraft 2) The two airplanes collided while engaged in fish spotting in a rural area of Alaska. The pilot and observer of the Cessna 185, N59AK, said they were cruising over water at 2,000 feet msl in straight and level flight, about to exit a bay. They said they did not see the other airplane until an instant before impact, and that the Bellanca, N5025K, seemed to approach them from slightly below, and slightly to the right, or about their 1 o'clock position. The pilot related that he does not recall a conscious effort to avoid the collision, but that he probably 'instinctively' pulled back on the wheel. The Bellanca fell nearly straight into the sea. The Cessna pilot said the right float was slashed by the Bellanca's propeller. A portion of the Bellanca's right wing fuel tank was found imbedded in the right float of the Cessna. Both airplanes have high wings. The pilot of the Cessna said the weather was clear and sunny, with reflected sunglare from the water and snow covered mountains. ## Analysis (aircraft 1) The two airplanes collided while engaged in fish spotting in a rural area of Alaska.

The Cessna received minor damage to the right amphibian float; the commercial pilot and the private pilot passenger (observer) aboard were not injured. The airplane continued on to Birchwood Airport, Birchwood, Alaska, and landed without incident. The Bellanca airplane was destroyed, and the two occupants, a commercial certificated pilot and a passenger (observer), were fatally injured. The Bellanca fell into the waters of Prince William Sound, and the victims were removed by nearby fishing boats. The airplane was recovered by a landing craft type boat and taken to Valdez, Alaska. The two airplanes were operated under 14 CFR Part 91, and visual meteorological conditions prevailed. No flight plans were in effect for either airplane. The pilot of the Cessna, and the observer, were interviewed on April 9th by the NTSB investigator-in-charge (IIC) at the Birchwood Airport. The pilot reported he had started flying about 0900, and had stopped for lunch and fuel at a fishing vessel in Galena Bay. After the stop, he resumed his fish spotting duties. The pilot stated he and the pilot of the Bellanca airplane were among a group of 20 or more airplanes all flying in the same general area near Galena Bay to spot herring (the airplanes fly in support of nearby fishing vessels, and the pilots, or their observers, radio information to the boat crews where the herring are schooling. The herring fishing season had not opened, but an opening was deemed imminent). The other airplanes were dispersed in about a one mile circle, with altitudes estimated from 1,000 feet msl to 3,500 feet msl. The Cessna pilot related his airplane was at 2,000 feet msl, in level flight, with 20 degrees of flap extended. He said his airplane's wingtip and vertical stabilizer strobes were turned on, as well as the navigation lights. His airplane was heading in a southwesterly direction, exiting the mouth of Galena Bay. The pilot said he was flying the airplane from the left seat, and that his passenger, whom he employed as an observer, and who is also a private pilot, was seated in the right front seat. He said neither he or the observer saw the Bellanca until an instant before impact, when they saw "a flash of yellow." He said he believes the collision was nearly head on, with the Bellanca slightly below and to his right. He said the impact happened so quickly that he does not recall a conscious attempt to avoid the Bellanca, but that he probably "instinctively" pulled back on the control yoke. After impact, the pilot said he became aware that the other airplane had crashed. He radioed for a nearby airplane, piloted by Mr. Terry Holiday, owner of Holiday Aviation, Birchwood, to fly alongside of him and assess the damage to his airplane. The damage appeared to be limited to the right amphibian float, and a decision was made to fly the airplane to Birchwood (approximately 110 miles west of the accident site) for landing and subsequent repairs. The observer in the Cessna, a private pilot, related essentially the same information as the pilot. The observer said his job was to look for fish and other aircraft, assist in the communications, and to take over the controls if required in an emergency. He said he had no flying duties, and that he did not see the Bellanca until an instant before impact. The Cessna 185's right float sustained damage to its hydraulic landing gear actuating system, and its wheels were hanging down, partially extended, but not locked. The left float was undamaged. The pilot elected to leave the left float's landing gear retracted, and landed without mishap on a hard surfaced runway at Birchwood. According to witnesses on the fishing vessels (see attached Alaska State Trooper's report) the Bellanca fell nearly vertically into the water close to a fishing boat. None of the witnesses actually saw the impact between the two airplanes. Crewmen from the fishing boats were able to recover the victims, and fastened the Bellanca to a boat with a line. PERSONNEL INFORMATION The pilot of the Cessna was James P. Blue, of Homer, Alaska. Mr. Blue was a member of the Alaska Fish Spotter's Association, and has been spotting fish for several years. Mr. Blue was involved in another mid air collision in 1991 near the same location (Tatitlek). That accident also occurred on April 9. There was a single fatality in the other airplane. Mr. Ronald J. Gribble was the pilot of the Bellanca. Mr. Gribble was also a resident of Homer, and was a member of the Alaska Fish Spotter's Association. Mr. Gribble had several years experience spotting fish in Alaska. AIRCRAFT INFORMATION The Cessna 185 had been modified by replacing the original, solid, lower main cabin doors with transparent lower panels on both sides of the airplane, and overhead skylights to increase visibility. The airplane has a high wing, and was painted principally yellow, with areas of aqua and black trim. It was equipped with night navigation (position) lights, wing tip strobes, and a strobe on the vertical stabilizer. The Bellanca is a high wing airplane, and was painted principally yellow with areas of black trim. It was equipped with night navigation (position) lights, a strobe light on the vertical stabilizer, and cabin skylights. METEOROLOGICAL INFORMATION The pilot of the Cessna indicated in his verbal statement to the NTSB investigator-in-charge that at the time of the collision, he was flying the airplane in a southwest direction. In his written statement to the NTSB, he related he was flying in a westerly direction, about to exit Galena Bay. He also noted in his written statement that his visibility was hampered by bright sun reflecting off the ocean and snow covered terrain. At the time of the accident, 1255 (estimated) Alaska daylight time, a review of solar tables places the sun at an azimuth of 163.6 true (138.6 magnetic), and 36 degrees above the horizon. Witnesses, and the pilot of the Cessna, described the prevailing weather as clear and sunny, with light winds. COMMUNICATIONS The Cessna pilot stated that at the time of the accident, he was monitoring the State of Alaska's Fish and Game radio frequency, as well as the common traffic advisory frequency the other fish spotting airplanes were using. He said he was not in communication with the pilot of the Bellanca. It is unknown what frequency(s) the Bellanca pilot was monitoring. Both airplanes were operating in Class E, General Controlled Airspace. They were not in contact with any air traffic control facility, nor were they required to be. At the altitude they were flying, radar coverage was not available in the accident area. WRECKAGE AND IMPACT INFORMATION The NTSB IIC inspected the Cessna airplane at the Birchwood Airport on April 9. The airplane was parked outside, on the parking ramp. The only damage visible was to the right, yellow colored, float. The damage to the right float was described by the pilot of the Cessna as "prop slashes." Five slashes were noted on the right float. The first slash, (moving from the toe of the float aft) was located about 70 inches aft of the toe, nearly abeam the right front, outboard spreader bar attachment. Adjacent to, and below the first slash, on the bottom of the float, was a large, irregular shaped hole, about 2-1/2 feet long by 2 feet wide. Inside the hole was a piece of crumbled metal and tubing. This metal was later identified as a portion of the Bellanca's right wing fuel tank. The second slash was about 30 inches aft of the first. The remaining three slashes continued nearly equidistant ## Aircraft 1 - Registration: [N59AK](https://openairdocs.org/aircraft/N59AK), registered now, S/N 18503604 (OpenAirDocs) - Reported make and model: Cessna 185 - Registry model: [Cessna A185F](https://openairdocs.org/model/cessna-a185f) (registry code 2072821) (OpenAirDocs) - Category: Airplane - Serial number: 18503604 - Airframe hours: 5750 - Engines: Continental IO-520-D30 300 horsepower reciprocating - Damage: Minor damage - Flight: Part 91 - Registered owner: James P.
