# NTSB CHI94LA084: Piper PA-38-112, N23797, Eden Prairie, MN, February 13, 1994 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: February 13, 1994, 16:33 local (22:33 UTC) - Place: Eden Prairie, MN - Coordinates: 44.86024, -93.429084 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=44.8602&lon=-93.4291&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report February 14, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9466 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI94LA084 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9466/pdf - Page: https://openairdocs.org/ntsb/CHI94LA084 ## Probable cause THE PILOT'S POORLY PLANNED APPROACH AND REMAINING BELOW A PROPER GLIDE PATH DURING FINAL APPROACH. THE PILOT'S LACK OF TOTAL EXPEREINCE WAS A FACTOR. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, approach - vfr pattern - final approach - object - wire,static - proper glidepath - below, pilot in command (cause) - planned approach - poor, pilot in command (cause) - lack of total experience, pilot in command - In flight collision with terrain/water, descent - uncontrolled ## Analysis WHILE ON FINAL APPROACH TO THE ORIGINATING AIRPORT AFTER A SOLO CROSS COUNTRY FLIGHT, THE AIRPLANE STRUCK UNMARKED POWERLINES. THE AIRPLANE THEN DESCENDED TO IMPACT WITH THE TERRAIN. THE POWERLINES WERE LOCATED 1.2 MILES FROM THE RUNWAY THRESHOLD AND WERE 44 FEET ABOVE THE RUNWAY ELEVATION. ## Factual narrative On February 13, 1994, at 1633 hours central standard time, a Piper Tomahawk PA-38-112, N23797, operated as a rental aircraft by Thunderbird Aviation, Inc., of Minneapolis, Minnesota, impacted static lines between power poles on final approach to Runway 27R at Flying Cloud Airport, Eden Prairie, Minnesota. A section of the right wing leading edge and upper surface departed the aircraft. The aircraft came to rest approximately 300 feet further on the flight path and was destroyed. The pilot was seriously injured. Visual meteorological conditions prevailed at the time of the accident and a VFR flight plan was on file. The flight was operated under 14 CFR Part 91, and originated from Eden Prairie, MN, as a student solo cross country. At 1550 hours the pilot departed on a return leg from a refueling stop at Olivia, MN (Y39). A review of the Air Traffic Control tape indicates the pilot initially contacted the tower and incorrectly reported his position as 10 miles southwest of tha airport. Initial tower instructions were to expect a landing on runway 27L. The tower determined the airplanes' actual position to be north-northwest of the airport using tower radar. The controller gave the pilot vectors to the field and handed him off to the north tower controller. The pilot was cleared to land on runway 27R. An aircraft in the pattern following the mishap aircraft asked the tower what the Tomahawk's intentions were. The tower controller responded that he was landing. The tower controller then asked the Tomahawk if he still had the airport in sight, to which the pilot responded, "Roger, making final." The tower controller cautioned "you're a little bit low, you might want to pull up." The following traffic then notified the tower that he saw the mishap aircraft hit the wires. There were no visual markers on the wires. The supporting towers were marked with red obstruction lights. The approximate height of the wires were 950 ft above mean sea level(MSL). The runway threshold elevation is 906 ft MSL. The distance from the threshold was approximately 7250 ft. No VASI was installed on Runway 27R. Sunset was at 1738 central standard time. The airplane had accrued 8 hours since annual inspection, where no discrepancies were noted. Post crash inspection of the aircraft showed presence of fuel at the site, engine continuity, flight control continuity and the ability of the undamaged magneto to produce spark. The FAA Airworthiness Inspector's on scene report is enclosed. ## Aircraft - Registration: [N23797](https://openairdocs.org/deregistered/N23797-1999-03-01), registration cancelled 1999-03-01, S/N 38-79A1054 (OpenAirDocs) - Reported make and model: PIPER PA-38-112 - Registry model: [Piper PA-38-112](https://openairdocs.org/model/piper-pa-38-112) (registry code 7103812) (OpenAirDocs) - Category: Airplane - Serial number: 38-79A1054 - Engines: LYCOMING O-235-L2C 112 horsepower reciprocating - Damage: Destroyed - Flight: Personal, Part 91 - Operator: Thunderbird Aviation - Registered owner: Thunderbird Aviation - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: Annual, January 27, 1994, 8 hours before - Departed: Y39, OLIVIA, MN - Flight plan: VFR - Airport: FCM, Flying Cloud, runway 27R ## Flight crew As NTSB recorded them.

Struck power line and crashed during approach to land. Student was aware of the power line. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
