THE CROSSWIND WAS A RELATED FACTOR. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - flare/touchdown - weather condition - crosswind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - uncontrolled, pilot in command - On ground/water collision with object, landing - object - aircraft parked/standing ## Analysis THE PILOT OF A CESSNA 170B, N4473B, LANDED ON RUNWAY 27 WITH A RIGHT CROSSWIND. HE SAID THAT DURING THE FLARE, THE WIND BLEW THE PLANE TO THE LEFT. DURING TOUCHDOWN, ITS LEFT WING HIT THE RUNWAY & THE PLANE ANGLED TO THE LEFT, CROSSED A PARALLEL TAXIWAY, ENTERED A RAMP AREA, AND HIT A PARKED PIPER PA-28, N6947J. THE CESSNA'S PROP SEVERED THE LEFT WING OF THE PA-28, OUTBOARD OF THE LEFT GEAR. NO PRE-ACCIDENT MECHANICAL PROBLEM WAS EVIDENT. ABOUT 23 MILES WEST AT PADUCAH, KY, THE 1550 EDT WEATHER WAS IN PART: 1500 FT SCATTERED, 15 MI VISIBILITY, WIND FROM 350 DEG AT 11 KTS. ## Factual narrative On Friday, September 10, 1993, at approximately 1545 eastern daylight time (edt), a Cessna 170B, N4473B, owned and operated by Gerald and Genevee Broshar of Anderson, Indiana, went off the runway and collided with a parked Piper PA-28, N6947J, as the Cessna pilot was landing at the Kentucky Dam State Park Airport, Gilbertsville, Kentucky. Both airplanes were substantially damaged. The passenger was seriously injured with a broken arm, but the pilot received no significant injury. Visual meteorological conditions prevailed. No flight plan was filed, nor was one required. The flight was conducted in accordance with 14 CFR 91. The purpose of the flight was for the pilot and passenger to go to a Cessna 170 fly-in. During a landing on runway 27, the airplane encountered a crosswind from the north and began to drift to the left. It then angled off the left side of the runway, crossed a parallel taxiway, and subsequently collided with a parked aircraft on a parking ramp. The parked aircraft was about 330 ft from the runway. During impact, the propeller of the Cessna 170 contacted the left wing of the Piper PA-28. The left wing of the Piper was severed just outboard of the landing gear and was destroyed. The propeller of the Cessna was severly damaged with nicks and gouges along the leading edges of the blades. The engine cowling of the Cessna was damaged around the lower circumference of the engine. Also, the underside of the Cessna's left wing tip and aileron were damaged. This damage matched marks on the runway surface, where the left wing appeared to have made contact. The pilot reported that when he was ready to flare for a landing on runway 27, a crosswind from the north blew the airplane to the left. He also noted that there were trees along the north side of the runway. At Paducah, Kentucky, the 1550 EDT weather was in part: 1500 feet scattered, 7 miles visibility, wind from 350 degrees at 11 kts, temperature 76 degrees, dew point 47 degrees, altimiter 30.11" Hg. No pre-accident mechanical problem of the Cessna 170 was evident. ## Aircraft - Registration: [N4473B](https://openairdocs.org/aircraft/N4473B), registered now, S/N 26817, built 1955 (OpenAirDocs) - Reported make and model: CESSNA 170B - Registry model: [Cessna 170B](https://openairdocs.org/model/cessna-170b) (registry code 2072306) (OpenAirDocs) - Registry engine: [Continental 0-300 series](https://openairdocs.org/engine/continental-0-300-series) (registry code 17022, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 26817 - Engines: CONTINENTAL O-300-A 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Gerald & Genevee Broshar - Registered owner: Gerald & Genevee Broshar - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 22, 1993, 24 hours before - Departed: AID, ANDERSON, IN - Destination: M34 - Airport: M34, Kentucky Dam State Park, runway 27, 4,000 × 100 ft, asphalt ## Flight crew As NTSB recorded them.

Lost directional control landing in gusty crosswind. Ran off runway 300 feet and struck a parked aircraft. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
