# NTSB NYC01LA138: Interplane Sky Boy, Sayre, PA, June 5, 2001 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: June 5, 2001, 19:00 local (23:00 UTC) - Place: Sayre, PA - Coordinates: 41.98611, -76.565002 - Nearby events: https://openairdocs.org/map.md?lat=41.9861&lon=-76.5650&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report November 28, 2001 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 52427 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC01LA138 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52427/pdf - Page: https://openairdocs.org/ntsb/NYC01LA138 ## Probable cause The pilot's failure to maintain an adequate climb airspeed. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, takeoff - initial climb - airspeed - not maintained, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - grass ## Analysis During the initial climbout after takeoff, the ultralight was observed rolling from side to side. It then rolled inverted and impacted the runway. The pilot reported that he "failed to maintain optimal climbing speed." ## Factual narrative On June 5, 2001, about 1900 eastern daylight time, an Interplane Skyboy, an unregistered ultralight, was substantially damaged during takeoff from Blue Swan Airport, Sayre, Pennsylvania. The non-certificated pilot received serious injuries. Visual meteorological conditions prevailed for the instructional flight. No flight plan had been filed for the local flight that was conducted under 14 CFR Part 103. According to the pilot: "Upon take off I failed to maintain optimal climbing speed. Aircraft rolled to the right [and] the left and made contact [with the] ground." According to a witness, the pilot initiated a takeoff from runway 28, with winds coming from straight ahead at 4 knots. The ultralight became airborne in a nose-high attitude after a ground run of a few hundred feet. Once airborne, the wings rocked from side to side, and the ultralight climbed to about 25 feet above the runway surface. The ultralight then rolled 180 degrees to the right, and descended onto the runway in an inverted, nose down attitude. The witness then ran to the wreckage and extracted the pilot. The witness also reported that the accident pilot flew the ultralight earlier the same day for 0.5 hours. After that flight, the witness flew it and noted no problems. The accident pilot then departed on the accident flight. The pilot purchased the ultralight in Florida, and received his initial flight training there. He soloed the ultralight on April 28, 2001. It was then disassembled, and transported to Pennsylvania. It was not flown again until the date of the accident. The pilot had 15.4 hours of flight experience, including 1 hour of solo flight, all in make and model. The pilot's logbook contained an endorsement for solo flight from his flight instructor. The pilot did not possess a Federal Aviation Administration (FAA) airman's medical certificate or a student pilot certificate, nor were they required. The ultralight was manufactured in the Czech Republic, and sold as an "ultralight trainer." It was equipped with a pitot-static type airspeed indicator. It was not equipped with an attitude indicator, and climb attitude was maintained by outside visual reference. ## Aircraft - Registration: UNREG (not matched to a registry record) - Reported make and model: Interplane Sky Boy - Category: Ultralight - Serial number: 8/2000 - Airframe hours: 52.8 - Engines: Rotax 582UL-2V 65 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 103 - Registered owner: Walter Finch - Departed: N32, Sayre, PA - Destination: N32, Sayre, PA - Airport: N32, Blue Swan, runway 28, 2,850 × 150 ft, grass/turf ## Flight crew As NTSB recorded them. NTSB leaves out names. - Pilot; age 59; injuries: serious; seat: left; flight hours: 15 total, 15 in this make and model, 1 as pilot in command, 15 in the last 90 days ## Weather - Conditions: Visual (VMC), Day - Wind: 340° at 4 knots - Visibility: 10 statute miles - Lowest ceiling: 12,000 ft overcast - Temperature: 66 °F, dew point 52 °F - Altimeter: 30.04 inHg - Observed at: ELM, 18 nm away 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.
