Airplane Parts Manufacturer Ordered To Pay $27.7M To Man Injured In Crash: Glasair RG Super 11S, N333HK, accident occurred September 03, 2010 near Lake Elmo Airport (21D), Minnesota

MINNEAPOLIS (WCCO) — A Ramsey County jury awarded $27.7 to a Minnesota pilot who claimed faulty airplane parts contributed to a 2010 plane crash that left him with life-changing injuries.

According to a statement from attorneys, Mark Kedrowski was piloting a private plane that lost engine power, forcing him into an unpowered crash landing near Lake Elmo.

The plane was destroyed, and Kedrowski was left with debilitating injuries, including a below-the-knee amputation on his left leg, a fused ankle and severe injuries to his face and head. Attorneys say he required over 50 surgeries in all.

In a years-long lawsuit and a four-week trial in Ramsey County, Kedrowski alleged that airplane parts manufacturer Lycoming Engine’s fuel pump malfunctioned, causing the crash. Lycoming denied any responsibility, saying Kedrowski lost control of the airplane during flight.

Attorneys say Kedrowski was once an impressive athlete, participating in triathlons, paddle boarding, biking, skiing and once qualifying for the Olympic trials in windsurfing.

NTSB Identification: CEN10FA519
14 CFR Part 91: General Aviation
Accident occurred Friday, September 03, 2010 in Lake Elmo, MN
Probable Cause Approval Date: 06/13/2011
Aircraft: KWECH GLASAIR RG SUPER 11S, registration: N333HK
Injuries: 1 Serious.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The pilot was departing in his experimental amateur-built airplane on a personal cross country flight. Witnesses in the area of the accident reported they observed the low-flying yellow airplane climb over a tree line, pass over the roadway they were on, encounter wind, and then bank. The airplane subsequently descended during the turn and impacted terrain in a field about 1/2 mile north of the departure runway, where it sustained substantial damage to its fuselage. The recorded wind was 19 knots gusting to 28 knots. The pilot sustained serious injuries and indicated that he did not recall anything regarding the accident flight. A postaccident examination of the wreckage revealed no evidence of mechanical malfunctions or anomalies with the airframe or engine.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to maintain control of the airplane during takeoff with gusty wind conditions, which resulted in a collision with terrain.


On September 3, 2010, about 1605 central daylight time, an experimental amateur-built Kwech GLASAIR RG SUPER 11S airplane, N333HK, piloted by a private pilot, sustained substantial damage on impact with terrain during initial climbout from runway 32 (2,850 feet by 75 feet, asphalt) at Lake Elmo Airport (21D), near Lake Elmo, Minnesota. The personal flight was operating under 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time of the accident. An instrument flight rules flight plan was on file and was activated. The pilot sustained serious injuries. The flight was originating from 21D at the time of the accident, and was destined for the Pine River Regional Airport, near Pine River, Minnesota.

Witnesses in the area of the accident reported to Washington County Sheriff’s Office representatives that they observed the low-flying yellow airplane. According to the witnesses, the airplane climbed over a tree line, passed over Manning Avenue, encountered wind, and banked. The airplane subsequently descended during the turn and impacted terrain in a field south of 40th Street and east of Manning Avenue.

A Federal Aviation Administration (FAA) Inspector interviewed the pilot in a physical rehabilitation center. The pilot indicated that he did not recall anything regarding the accident flight.


The 39-year-old pilot held a FAA private pilot certificate with airplane single engine land and instrument ratings. The pilot held a third-class medical certificate issued to him on February 1, 2010, without limitations. An endorsement in his logbook showed that he completed a flight review on March 2, 2009 and that he completed an instrument competency check on September 3, 2009. The last entry in the pilot's logbook was dated December 18, 2009, and his total recorded flight time was 446.9 hours. A family member supplied a list of flights that the pilot was reported to have taken between January 6 and August 15, 2010.


N333HK was an experimental amateur-built Kwech GLASAIR RG SUPER 11S, single-engine, low-wing, retractable tri-cycle landing gear, two-place airplane, with serial number 2313. A Lycoming IO-360-B1E engine, rated at 205-horsepower, with serial number L-11581-51A, custom built by DeMars Aero LTD, powered the airplane. 

Maintenance records for the airplane were requested and were not located.


At 1553, the recorded weather at the St. Paul Downtown Airport / Holman Field, near St Paul, Minnesota, about 240 degrees and 10 miles from the accident site, was: Wind 300 degrees at 19 knots gusting to 28 knots, visibility 10 statute miles, sky condition broken 3,400 feet, overcast 4,300 feet, temperature 16 degrees C, dew point 9 degrees C, altimeter 29.94 inches of mercury.


The airplane wreckage came to rest in a field about one half mile north of the departure runway. Pictures of the wreckage path showed that the propeller separated from the engine and the engine separated from the fuselage. The propeller and engine were found in the northwest portion of the debris field and the airframe in the southeast portion of the debris field. The propeller had chordwise abrasion and leading edge nicks on its blades. The fuselage exhibited deformation and crushing consistent with substantial damage. FAA Inspectors examined the wreckage and did not find any pre-impact anomalies.


The engine was recovered and sent to a local fixed base operator for a test run. Damaged parts that included a cracked oil sump, a magneto with a broken flange, a fuel injector line, and damaged ignition leads were replaced with exemplar parts. The engine was installed in a test cell and it was observed by the National Transportation Safety Board Investigator In Charge to be operational during the test run. The damaged magneto was mounted on a lathe and it produced spark when the lathe rotated.
