On July 25, 2015, about 0910 eastern daylight time, a Piper PA-38-112, Canadian registration C-GTAO, collided with the terrain in Millbury, Ohio, while attempting to return to the Toledo Executive Airport (TDZ), Toledo, Ohio. The pilot was seriously injured and succumbed to those injuries on August 5, 2015. The airplane was substantially damaged. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight. The flight originated from TDZ just prior to the accident and the intended destination was the Region of Waterloo International Airport (CYKF), Ontario, Canada.

After takeoff, the pilot contacted air traffic control and requested flight following. Shortly after radar contact was established, the pilot reported a "mayday" over the air traffic control frequency. The pilot stated that he needed to return to the airport and that he did not require any assistance. The airplane impacted a corn field about 1/2 mile east of the approach end of runway 32 at TDZ.

Personnel Information

The pilot held a private pilot certificate with a single-engine land rating. He was issued a third class airman medical certificate on December 8, 2014, with a limitation for corrective lenses.

A copy of a pilot logbook was provided during the investigation. The first entry in the logbook was dated June 10, 2009. The logbook began with 492 hours of flight time carried over. The last entry in the logbook was dated July 24, 2015. The pilot's total flight time as of that date was 1,103.1 hours. Of the 611 flight hours documented in the logbook, 605 hours were in the accident airplane. The pilot had his last flight review on January 19, 2015.

Aircraft Information

The accident airplane was a Piper PA-38-112, serial number 38-79A1002. The PA-38-112 is a single-engine, two-place airplane, with tricycle landing gear. The airplane was powered by a 112-horsepower, Lycoming O-235-L2C, four-cylinder, reciprocating engine, serial number L-19639-15. The airplane was equipped with a two-blade Sensenich model 72CK-O-56 propeller assembly. Prior to October 2004, the aircraft held German registration number D-ETAV.

The last aircraft and engine annual inspections were completed on March 18, 2015, at a total time of 1,720.5 hours. A flight log indicated the aircraft total time on the day before the accident was 1,745.6. The hour meter at the time of the accident was 1,097.3 and the tachometer time was 312.5.

According to maintenance records, the emergency locator transmitter (ELT) was checked on February 6, 2015. The ELT was in the armed position and the battery expiration date on the label was April 2015. There were no reports of the ELT having activated during the accident.

The accident occurred on the first flight since the fuel tanks were filled the day before.

Weight and Balance calculations for the accident flight indicate the airplane was about 29.5 pound over the maximum allowable gross weight.

Meteorological Information

The TDZ Automated Surface Observing System (ASOS), is located about 1 miles from the accident site. At 0953, the TDZ ASOS recorded weather conditions as: wind from 230 degrees at 11 knots; visibility 10 miles or greater; clear sky; temperature 26 degrees Celsius (C); dew point 17 degrees C; altimeter 29.97 inches of mercury.

Wreckage and Impact Information

The airplane came to rest in an open field which contained a young corn crop. The empennage was separated just aft of the cockpit area. The left wing sustained minor damage. The right wing was partially separated at the fuselage. The outboard section of the wing was twisted upward and back. The leading edge of the wing was crushed. The engine cowling was crushed rearward. The cockpit area remained intact.

The wreckage was examined by inspectors from the Federal Aviation Administration (FAA) who reported the following:

The flight controls remained attached to their respective surfaces. Flight control continuity was established. The flaps were extended to the first notch.

The propeller gear was separated from the crankshaft. The oil dipstick was secured in the filler tube which was broken at its base. The dipstick indicated there were 4 quarts of oil in the engine. The left and right cowl doors contained an oil film. The right rear engine accessories, accessory cover, crankcase, battery box, and engine mount contained an oil film. No oil was visible on the windscreen or on the outside of the fuselage.

An engine examination revealed fuel was present in the carburetor. The spark plugs were fouled to the point that the electrodes were bridged. The crankshaft was rotated by hand. One cylinder exhibited strong compression. Another cylinder exhibited minimal compression and the remaining two cylinders had no compression. The No.1 cylinder exhaust valve adjustment mechanism (jam nut and screw) was laying loose in the cylinder head cover. The No.3 cylinder intake valve adjustment mechanism was backed off the rocker arm. The No.4 cylinder intake valve adjustment mechanism jam nut was backed off the rocker arm and the valve spring retainer was broken. The cylinder head gaskets on the No. 3 and No. 4 cylinders were puckered and leaking. The valve clearance and engine timing were out of tolerance.

Medical and Pathological Information

The pilot initially survived the accident, but succumbed to his injuries on August 5, 2015. The NTSB was not immediately notified of the pilot's death; therefore, an autopsy and toxicological tests were not requested.

Additional Information


Lycoming Service Instruction 1068A recommends that the tappet clearance should be checked after each 100 hours of operation. The instructions stated the jam nuts should be torqued to 450 inch pounds.

A Kitchener man is in critical condition in an Ohio hospital after the plane he was piloting crashed into a corn field Saturday morning.

Police said Hans Asam, 64, of Kitchener was alone in a single-engine Piper Tomahawk when it went down in a field a short distance from the Toledo Executive Airport.

"Based on witness accounts, there was some kind of engine trouble," said Sgt. Ryan Purpura of the Ohio State Highway Patrol.

Witnesses said it looked as though the plane was trying to reach the airport when it crashed nose first.

The impact ripped off the propeller, spun the plane about 180 degrees and heavily damaged the right wing.

The fuselage was broken in half, Purpura said.

Asam was taken to the Mercy St. Vincent Medical Centre in nearby Toledo. He was listed in critical condition on Monday afternoon in the hospital's intensive care unit.

Both the Federal Aviation Administration and the National Transportation Safety Board are participating in an investigation into the cause of the crash.

Board spokesperson Terry Williams said his agency is gathering information from the Federal Aviation Administration, which had personnel at the crash scene.

Williams said the investigation will look at aspects such as where the plane came to rest and its mechanical condition. Investigators also plan to interview Asam when possible.

Federal Aviation Administration spokesperson Elizabeth Isham Cory said it will be several weeks before they're in a position to release any information about the investigation.

Records list Hans-Ulrich Asam of Kitchener as the registered owner of the plane. According to the Canadian Civil Aircraft Register, the plane built in 1979 is based in Stratford.

The plane's last documented flight prior to the crash took it from Frankfort, Ky., to the Toledo Executive Airport on Friday afternoon.




MILLBURY, Ohio — A pilot was injured today after his single-engine plane crashed into a corn field near Lake High School.

Witnesses reported hearing the engine sputter before the crash, which happened just behind the school's football field.

Mike Kohlhofer was training with his sons, Ryan and Gavin, at the school's stadium when they heard the sputtering and eventually saw it take a nosedive into the corn, he said.

Ryan, 20, called 911 just after 9 a.m. Mr. Kohlhofer said the man was conscious but not speaking, partially out of the plane but still buckled in.

"I just tried to keep his attention, keep him alert," he said. "I did make eye contact so I was encouraged he was going to be OK at that point."

Sgt. Ryan Purpura of the Ohio State Highway Patrol Bowling Green Post said the pilot was traveling northwest and appeared to be trying to return to the airport when he crashed.

He said police haven't spoken to the pilot yet but the man is expected to survive. It is believed the pilot is not from the area, Sergeant Purpura said.

"It sounds like anything you can walk away from is obviously good," he said.

The single-engine Piper Tomahawk’s right wing was severely damaged and the propeller separated from the rest of the body.

Investigators from the Federal Aviation Administration are expected to arrive on scene later today.

Paramedics on the scene said the pilot was taken to Mercy St. Vincent Medical Center in Toledo. No one else was on board the plane.
