From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Acft crashed on takeoff. Other circumstances are unknown. (.19) on January 13, 1999, about 1435 Alaska standard time, a wheel equipped Piper PA-22-160 airplane, N9190D, sustained substantial damage when it went off the side of runway 13 during takeoff from the lake Hood airstrip, Anchorage, Alaska. The airplane was being operated as a local, visual flight rules (VFR) personal flight under title 14, CFR part 91, when the accident occurred. The solo student pilot was not injured. Visual meteorological conditions prevailed, and no flight plan was filed. During a telephone conversation with the national transportation safety board investigator-in-charge on January 14, the pilot reported that he intended to do a few touch-and-go landings. The pilot noted that during the initial takeoff roll, the airplane pulled to the left, and continued off the left side of the runway. He stated that the main landing gear contacted soft snow, and the airplane nosed over. A federal aviation administration (FAA) airworthiness inspector, Anchorage flight standards district office (FSDO), inspected the airplane at the accident site. He reported that the airplane's left brake and wheel assembly appears to have been either locked or frozen. He stated that a detailed inspection of the entire wheel assembly is pending. The airplane sustained substantial damage to the right wing, and right wing lift struts. (-23) the pilot reported he noticed some snow on the inner wheels. He had taxied some distance to the end of the runway melting the snow. He set the brakes at the end of the runway and accomplished his engine run up freeing the accumulated water on the left hand brake. He then started his takeoff roll and the aircraft veered to the left. He applied right hand brake but had attained too much momentum to correct the deviation. The aircraft exited the left side of the runway into hard packed snow and subsequently flipped over onto its back. The runway surface is packed snow mixed with gravel, there was an evident skid mark from the left tire from the point of departure to the point of entering the hard packed snow at the left side of the runway. (.4) the student pilot reported that he intended to do a few touch-and-go landings. He stated that during the initial takeoff roll, the airplane pulled to the left, and continued off the left side of the runway. He said that the main landing gear contacted soft snow, and the airplane nosed over. An FAA airworthiness inspector inspected the airplane at the accident site. He said that an inspection revealed that the brake assembly had an accumulation of ice that restricted the left wheel from rotating. He added that as soon as the ice melted, the wheel rotated freely.

As the FAA filed it

ACFT CRASHED ON TAKEOFF. OTHER CIRCUMSTANCES ARE UNKNOWN. (.19) ON JANUARY 13, 1999, ABOUT 1435 ALASKA STANDARD TIME, A WHEEL EQUIPPED PIPER PA-22-160 AIRPLANE, N9190D, SUSTAINED SUBSTANTIAL DAMAGE WHEN IT WENT OFF THE SIDE OF RUNWAY 13 DURING TAKEOFF FROM THE LAKE HOOD AIRSTRIP, ANCHORAGE, ALASKA. THE AIRPLANE WAS BEING OPERATED AS A LOCAL, VISUAL FLIGHT RULES (VFR) PERSONAL FLIGHT UNDER TITLE 14, CFR PART 91, WHEN THE ACCIDENT OCCURRED. THE SOLO STUDENT PILOT WAS NOT INJURED. VISUAL METEOROLOGICAL CONDITIONS PREVAILED, AND NO FLIGHT PLAN WAS FILED. DURING A TELEPHONE CONVERSATION WITH THE NATIONAL TRANSPORTATION SAFETY BOARD INVESTIGATOR-IN-CHARGE ON JANUARY 14, THE PILOT REPORTED THAT HE INTENDED TO DO A FEW TOUCH-AND-GO LANDINGS. THE PILOT NOTED THAT DURING THE INITIAL TAKEOFF ROLL, THE AIRPLANE PULLED TO THE LEFT, AND CONTINUED OFF THE LEFT SIDE OF THE RUNWAY. HE STATED THAT THE MAIN LANDING GEAR CONTACTED SOFT SNOW, AND THE AIRPLANE NOSED OVER. A FEDERAL AVIATION ADMINISTRATION (FAA) AIRWORTHINESS INSPECTOR, ANCHORAGE FLIGHT STANDARDS DISTRICT OFFICE (FSDO), INSPECTED THE AIRPLANE AT THE ACCIDENT SITE. HE REPORTED THAT THE AIRPLANE'S LEFT BRAKE AND WHEEL ASSEMBLY APPEARS TO HAVE BEEN EITHER LOCKED OR FROZEN. HE STATED THAT A DETAILED INSPECTION OF THE ENTIRE WHEEL ASSEMBLY IS PENDING. THE AIRPLANE SUSTAINED SUBSTANTIAL DAMAGE TO THE RIGHT WING, AND RIGHT WING LIFT STRUTS. (-23) THE PILOT REPORTED HE NOTICED SOME SNOW ON THE INNER WHEELS. HE HAD TAXIED SOME DISTANCE TO THE END OF THE RUNWAY MELTING THE SNOW. HE SET THE BRAKES AT THE END OF THE RUNWAY AND ACCOMPLISHED HIS ENGINE RUN UP FREEING THE ACCUMULATED WATER ON THE LEFT HAND BRAKE. HE THEN STARTED HIS TAKEOFF ROLL AND THE AIRCRAFT VEERED TO THE LEFT. HE APPLIED RIGHT HAND BRAKE BUT HAD ATTAINED TOO MUCH MOMENTUM TO CORRECT THE DEVIATION. THE AIRCRAFT EXITED THE LEFT SIDE OF THE RUNWAY INTO HARD PACKED SNOW AND SUBSEQUENTLY FLIPPED OVER ONTO ITS BACK. THE RUNWAY SURFACE IS PACKED SNOW MIXED WITH GRAVEL, THERE WAS AN EVIDENT SKID MARK FROM THE LEFT TIRE FROM THE POINT OF DEPARTURE TO THE POINT OF ENTERING THE HARD PACKED SNOW AT THE LEFT SIDE OF THE RUNWAY. (.4) THE STUDENT PILOT REPORTED THAT HE INTENDED TO DO A FEW TOUCH-AND-GO LANDINGS. HE STATED THAT DURING THE INITIAL TAKEOFF ROLL, THE AIRPLANE PULLED TO THE LEFT, AND CONTINUED OFF THE LEFT SIDE OF THE RUNWAY. HE SAID THAT THE MAIN LANDING GEAR CONTACTED SOFT SNOW, AND THE AIRPLANE NOSED OVER. AN FAA AIRWORTHINESS INSPECTOR INSPECTED THE AIRPLANE AT THE ACCIDENT SITE. HE SAID THAT AN INSPECTION REVEALED THAT THE BRAKE ASSEMBLY HAD AN ACCUMULATION OF ICE THAT RESTRICTED THE LEFT WHEEL FROM ROTATING. HE ADDED THAT AS SOON AS THE ICE MELTED, THE WHEEL ROTATED FREELY.
