Associated factors are the pilot's habit interference and the FAA inspector's inadequate monitoring of the flight. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Wheels down landing in water, landing - flare/touchdown - gear retraction - not performed, pilot in command (cause) - habit interference, pilot in command (contributing factor) - wheels down landing in water - inadvertent, pilot in command - monitoring - inadequate, faa(principal operations inspector) (contributing factor) - Nose over, landing - flare/touchdown - terrain condition - water ## Analysis The airline transport pilot was taking a check ride with an FAA inspector for a reinstatement of his flight instructor certificate. The check ride was being conducted in the pilot's amphibian float equipped airplane. Under the direction of the FAA inspector, the pilot was demonstrating the technique for a glassy water landing. Shortly after touchdown, the airplane slowly nosed over. Both the pilot and the inspector were uninjured, and were able to quickly evacuate the airplane. The pilot related he was given different departure instructions from the air traffic control tower when he took off from a hard surface runway at the beginning of the flight, and he elected to leave his wheels extended longer than normal because of the route of flight. He said he forgot to retract them prior to the water landing. The FAA inspector indicated he also was unaware of the extended wheels. The landing gear indicator light in the airplane was functional at the time of the incident. ## Factual narrative On June 24, 1997, about 0915 Alaska daylight time, an amphibian float equipped Cessna 185 airplane, N4952E, received minor damage while landing on Figure Eight Lake, located about 15 miles northwest of Anchorage, Alaska. The airline transport certificated pilot-in-command (PIC), and the airline transport certificated Federal Aviation Administration inspector aboard the airplane were not injured. The local, 14 CFR Part 91 flight operated in visual meteorological conditions without a flight plan. The flight departed the Anchorage International Airport about 0845. The purpose of the flight was for the PIC to receive a Certificated Flight Instructor (CFI) renewal flight check from the FAA inspector. The NTSB investigator-in-charge spoke with the FAA inspector via telephone on June 24, and the pilot on June 25. Both the PIC and the FAA inspector related essentially the same information. The flight departed with the amphibian float wheels extended from Runway 24, intersection Charlie. The PIC accepted a clearance to turn to the right (north) prior to reaching Runway 14/32. The PIC said this clearance was acceptable, but instead of immediately retracting his wheels once he was airborne, he elected to keep the wheels extended longer than normal because the route of flight would place the airplane over a hard surface for a longer than normal period of time. The PIC said he was also concerned and distracted with radio transmissions and other airplane traffic as he departed Anchorage and neared Figure Eight Lake. The PIC said he forgot to retract the landing gear, and believes the distractions associated with the departure from Anchorage interrupted his normal routine of retracting the wheels. At the FAA inspector's request, he made an approach to land on Figure Eight Lake, and began to demonstrate and verbalize to the FAA inspector the technique for a glassy water landing. Upon touchdown, the airplane slowed, tipped forward, and went upside down. The FAA inspector related that he was also distracted looking for airplane traffic, and failed to notice that the PIC had not retracted the wheels. Both occupants were able to exit the airplane, and sat on the floats for a short time until another airplane landed on the lake and picked them up. The airplane is equipped with landing gear position indicator lamps which reflect whether the wheels are retracted or extended. The PIC indicated these lamps were operating properly throughout the flight and landing. The airplane was recovered and examined by an NTSB investigator. No preimpact mechanical anomalies were discovered, and the degree of damage was reclassified as minor. ## Aircraft - Registration: [N4952E](https://openairdocs.org/aircraft/N4952E), registered now, S/N 18503918, built 1979 (OpenAirDocs) - Reported make and model: Cessna 185 - Registry model: [Cessna A185F](https://openairdocs.org/model/cessna-a185f) (registry code 2072821) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18503918 - Airframe hours: 1596 - Engines: Continental IO-520-D 300 horsepower reciprocating - Damage: Minor damage - Flight: Part 91 - Registered owner: John S.
