Pratt & Whitney .
Its actually GE, Pratt and Whitney are 3rd with Rolls Royce second..I believe.

The largest single engine propeller driven aircraft is the Grumman AF-2S Guardian, a sub chaser of the Korean War era. It grossed at 25,500 lbs and was powered by a Pratt & Whitney R2800 engine of 2400 horsepower. It also had the largest Wing span for a single engine reciprocating aircraft at 60' 8".
Boeing has been making aircraft since the early 1900s. They are definitely the largest manufacturer. I believe the statistic is, "A Boeing aircraft takes off somewhere around the world every five seconds."
The biggest sized engine to have ever been in an aircraft is the GE90 series. Being the largest engine in aviation history, it was built by GE Aviation.

Aircraft engine manufacturers construct aircraft engines, and maintain the engines when faulty.
The A 380 is the world's largest aircraft.
The Douglas Skyraider and Vietnam version called the Spad are the most powerful piston driven propeller aircraft with highest load carrying capacity but not the largest. The Grumman AF-2S Guardian Torpedo Bomber of the Korean War era had slightly less horsepower with the Pratt Whitney R2800 engine, but it was a larger airplane and for purely piston powered reciprocating aircraft is the largest known single engine aircraft
The largest commercial aircraft that operates in the United States is the A380.
