WINDS WERE REPORTED 170 DEG AT 26 KTS GUSTING TO 40 KTS. THE PLT ADDED 20 KTS TO HIS V-REF SPEED OF 132 KTS & SELECTED AUTO-SPOILERDEPLOYMENT. PRIOR TO TOUCHDOWN CREW WAS ADVISED AGAIN OF A WINDSHEAR ALERT IN SEVERAL QUADRANTS. AFTER TOUCHDOWN THE ACFT BOUNCED & THE AUTO-SPOILERS DEPLOYED. THE ACFT TOUCHED DOWN AGAIN IN WHAT THE CREW DESCRIBED AS A FIRM LANDING. THEFLT ENGR FOUND NO APPARENT DAMAGE SO THE CREW DID NOT WRITE IT UP AS A HARD LANDING. ON 12/31 DAMAGE WAS FOUND ON THE UPPER CROWN OF THE FUSELAGE BETWEEN STATIONS 660 & 680 FROM STRINGER S-10 LEFT TO S-10 RIGHT. LATER INSPECTIONS REVEALEDNOSE GEAR DAMAGE ALSO. FLT RECORDER READ-OUT INDICATED THAT THE APPROACH SPEED VARIED FROM 143 TO 170 KTS WITH A TOUCHDOWN SPEED OF 163 KTS. SIGNIFICANT WINDSHEAR EXISTED BELOW 1,000 FT MSL & MODERATE TO SEVERE TURBULENCE EXISTED BELOW 5,000 FT MSL. UPDRAFTS & DOWNDRAFTS EXISTED BELOW 100 FT AGL DUE TO CONVERGENCE/DIVERGENCE OF THE WINDS. ## Aircraft - Registration: [N79750](https://openairdocs.org/deregistered/N79750-2018-01-24), registration cancelled 2018-01-24, S/N 22452, built 1981 (OpenAirDocs) - Reported make and model: BOEING 727-224 - Registry model: [Boeing 727-224](https://openairdocs.org/model/boeing-727-224) (registry code 1384076) (OpenAirDocs) - Registry engine: [Pratt & Whitney JT8D-5](https://openairdocs.org/engine/pratt-whitney-jt8d-5) (registry code 52046, turbo-jet) (OpenAirDocs) - Category: Airplane - Serial number: 22452 - Airframe hours: 7176 - Engines: P&W JT8D-15 15500 lbs thrust turbo fan - Damage: Substantial damage - Flight: Part 121 - Registered owner: Continental Airlines - Airworthiness certificate: Standard, Transport - Last inspection: Continuous airworthiness, December 25, 1983, 21 hours before - Departed: DEN, DENVER, CO - Flight plan: IFR - Airport: LGA, La Guardia, runway 13, 7,000 × 150 ft, concrete ## Flight crew As NTSB recorded them. NTSB leaves out names. - Pilot; age 46; commercial, flight engineer, airline transport; airplane ratings: multi-engine land, single-engine land; instrument ratings: airplane; medical: class 1, valid medical--w/ waivers/lim; seat: left; flight hours: 11,750 total, 6,100 in this make and model, 4,605 as pilot in command, 231 in the last 90 days, 79 in the last 30 days, 4 in the last 24 hours ## Weather - Conditions: Instrument (IMC), Night/dark - Wind: 180° at 28 knots, gusting 30 - Visibility: 2 statute miles - Lowest ceiling: 500 ft broken - Temperature: 50 °F, dew point 48 °F - Altimeter: 29.00 inHg - Observed at: LGA ## FAA reports on this event (1) The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs). - [Accident 19831228075919A](https://openairdocs.org/incident/19831228075919A), Dec 28, 1983: Boeing 727224, New York, NY, Substantial damage. Aircraft landed hard during wind shear condition. Pilot used poor technique using ground spoilers. ## Other investigations on N79750 (1) 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. - [NTSB FTW96RA039](https://openairdocs.org/ntsb/FTW96RA039), Nov 7, 1995: Boeing B727-224 (N79750), Panama City, Panama, incident 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.
