Wheels & brakes shop, 6 Loop Rd, Westchester County Airport, White Plains NY 10604 - overhaul of wheels, brakes, wheel speed sensors, brake control units and anti-skid boxes for BFGoodrich, Meggitt Aircraft Braking Systems, Meggitt Dunlop, Messier-Bugatti and Parker equipment. Confirmed directly against cosgroveaircraft.com: phone •••, FAA Wheel & Brake Repair Station FE1R136K and EASA.145.6087 (since 1985) both match exactly. Claimed authorized-distributor status for Goodyear, Michelin and Meggitt plus Gulfstream authorization could not be corroborated on the company site - treat as unconfirmed rather than dropped. · Mon-Fri 0700-1600 local

NDT shop - FAA repair station FE1R136K also carries NDI/NDT and specialized-services ratings per FAA aggregator record; exact NDT method scope (eddy current/dye penetrant/etc.) unconfirmed.

Avionics/instrument shop - bench repair of aircraft radio and electrical/instrument equipment on-airport at 38 Loop Road, Box 201, Westchester County Airport, White Plains NY 10604. Address and phone ••• confirmed exactly against a NY State corporate/SAM registry record, as is FAA Part 145 repair station GC1R161K holding Radio Class 1, Class 2, Class 3 plus Accessory Limited, Airframe Limited and Instrument Limited ratings. Correction: the same registry record dates the domestic-corporation filing to February 2, 1977, not 1947 as originally drafted - no source corroborates a 1947 founding, so the year has been fixed to reflect verified history (earlier informal operating history, if any, is unconfirmed).

Avionics/instrument shop - Duncan Aviation's HPN Avionics Satellite Shop (2 Hangar Rd) performs avionics troubleshooting, repairs, upgrades and installations, FDR/CVR downloads and data analysis, and pitot-static/transponder inspections on-site, with overhaul/exchange work routed to Duncan's main MRO facilities. White Plains, NY presence confirmed directly on duncanaviation.aero's own locations page, which lists it as an Additional Fixed Location (satellite shop); class rating unconfirmed.

Avionics/instrument shop (in-house, IBM Corporate Flight Operations) - Hangar W, 160 Airport Road; FAA repair station CW1R075K reportedly holds Limited-class Airframe, Accessory, Instrument and Radio ratings serving IBM's own Gulfstream fleet and Sikorsky helicopter. IBM is a genuine corporation headquartered a few miles away in Armonk, NY, and in-house Part 145 shops of this kind are a common pattern for large corporate flight departments, so this entry is kept; however the specific hangar address and certificate number CW1R075K could not be independently corroborated via public search - treat those specifics as unconfirmed pending direct verification.

Accessory/machine shop (in-house, IBM Corporate Flight Operations) - Hangar W reportedly houses a full machine shop and parts department supporting in-house component/accessory work under the same CW1R075K Limited-class Accessory rating; same caveat as above, hangar/certificate specifics unconfirmed via public search.

Engine/propeller shop, Westchester County Airport - the company's own site (flyhma.com, redirected from heavymetalair.com) confirms A&P line service plus engine work covering turboprop, piston and jet, and propeller maintenance, alongside FAA Part 145 certification and a Cessna/Beechcraft-focused service specialization. The specific Hangar T location and certificate number APJR371C could not be independently corroborated - treat as unconfirmed rather than dropped.

Avionics/instrument shop - same FAA repair station performs avionics work per the company site; described as a Cessna/Beechcraft-focused service center, consistent with (but not an explicit confirmation of) a formal Cessna-authorized parts & service center designation. Limited-class Instrument, Radio and Accessory rating attribution and the exact certificate number are unconfirmed.
