Location: Big Lake, AK
Accident Number: ANC20CA030
Date & Time: 02/28/2020, 1640 AKS
Registration: N7384D
Aircraft: Piper PA18
Aircraft Damage: Substantial
Defining Event: Loss of engine power (partial)
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal
The pilot reported that while performing touch-and-go maneuvers, he had applied carburetor heat during the second landing. During the takeoff, after the second landing, he turned the carburetor heat off and applied full power. Once airborne, the airplane began to lose power and he manipulated the throttle and carburetor heat levers but was unable to regain power. He chose to make a precautionary landing straight-ahead with partial engine power. During the landing on the remaining runway, the airplane departed the end of the runway, encountered unmaintained snow, and nosed over.
The airplane sustained substantial damage to the right wing lift strut and empennage.
A post-accident engine examination and test run was accomplished by the NTSB and FAA with no malfunctions or failures revealed.
The exact probability of carburetor icing was not able to be calculated for the accident airport due to the closest weather observation station being 8 miles away. The pilot however stated that while landing, there was about 3 inches of fresh snow on the runway, and that he believed the propeller wash likely introduced snow into the intake, which created carburetor ice. He added that he should have left the carburetor heat on longer after the second landing.

A Coast Guard Air Station Kodiak MH-60 Jayhawk helicopter crew rescued a pilot who crashed on Hallo Glacier Lake approximately 75 miles northwest of Kodiak Sunday afternoon.
The Jayhawk crew hoisted the man and transported him to Kodiak with no apparent injuries.
Watchstanders from Coast Guard Sector Anchorage received a MAYDAY call on VHF-Channel 16 from the pilot reporting the plane had safely landed, but tipped over after braking in the deep snow on the frozen lake.
The Jayhawk crew lowered an aviation survival technician to help right the aircraft off its nose before transporting the man to Kodiak.
“Through reliable communications, we were able to work with the Air Force Alaska Rescue Coordination Center to get the nearest rescue crew on scene to reach the pilot as efficiently as possible,” said Petty Officer 2nd Class Jonathan Zack, a Coast Guard Sector Anchorage watchstander. “We encourage the public to enjoy Alaska’s outdoors with the proper safety and communications equipment.”
Weather on scene was reported as 17-mph winds, 23 degrees and clear skies.
