Gulfstream G650ER
N54BR · ICAO: A6D5BC · Heavy jet

Apollo Mechanical Contractors is a full-mechanical contractor — HVAC, plumbing, process piping, sheet metal — working projects across the United States from a base in Kennewick, Washington. Bruce Ratchford started it in Richland in the mid-1970s, incorporating as Apollo Sheet Metal and opening for business as Apollo in 1981.
N54BR is reported as a Gulfstream G650ER. That is owner-supplied and the public registry does not currently corroborate it: the only FAA record for N54BR is a 2000 Stemme S10-VT motor-glider, c/n 11-041, registered to Admore International Inc, and the N-number inquiry returns reserved/multiple records. A reserved number that databases have not caught up with is exactly what a pending large-cabin delivery looks like, and 54BR matches Bruce Ratchford's initials — but neither of those is evidence, and this entry is weaker than every other row in the Pacific Northwest batch.
Hex A6D5BC is derived from the N-number and is correct for N54BR whatever airframe currently wears it. That cuts both ways: if the Stemme is the aircraft transmitting it, it will appear on this map as a G650ER until the registry is re-checked.
Base is the company's own region. Richland Airport itself is a 4,009ft strip, too short for a G650ER, so the home field here is Tri-Cities at Pasco — 7,707ft, twenty minutes from the Kennewick office and the only runway in the Tri-Cities that takes the type. The aircraft is reported as a frequent Boeing Field visitor.

Flight data is recorded when aircraft are detected by ADS-B. Check back later.
Yes. Celebplanes tracks 1 aircraft associated with Apollo Mechanical: a Gulfstream G650ER (N54BR). The aircraft is registered to Bruce Ratchford — Apollo’s founder and owner, not to Apollo Mechanical personally. Every movement is logged from the public ADS-B broadcast, so the flight history on this page is a record of the aircraft, not of who was aboard.
Apollo Mechanical flies a Gulfstream G650ER (registration N54BR). Live tracking, full flight history, and CO₂ emissions for each aircraft are available on this page.
Apollo Mechanical flies 1 tracked aircraft: N54BR (Gulfstream G650ER). The aircraft is registered to Bruce Ratchford — Apollo’s founder and owner, not to Apollo Mechanical personally. This is the count Celebplanes can evidence from public registration and ADS-B records; aircraft held through undisclosed entities or chartered rather than owned would not appear here.
Apollo Mechanical flies a Gulfstream G650ER — Ultra Long Range class, 7,500 nm range, seating up to 19 (registration N54BR). The aircraft is registered to Bruce Ratchford — Apollo’s founder and owner, not to Apollo Mechanical personally.
Apollo Mechanical's private jet tail number is N54BR (a Gulfstream G650ER). Each registration links to the live tracking page with full flight history, fuel burn and CO₂ emissions on Celebplanes.
Apollo Mechanical's Gulfstream G650ER (N54BR) burns roughly 470 gallons of Jet-A per hour, which converts to about 4,515 kg of CO₂ per flight hour — equivalent to roughly 11,176 miles of average passenger-car driving.

Yes. Every transponder-equipped aircraft broadcasts unencrypted ADS-B position data continuously, by FAA mandate. Celebplanes aggregates this public broadcast from ADSB Exchange, ADSB.fi, FlightRadar24 and airplanes.live — the same sources used by news outlets and academic researchers.
