I'm curious why the Garrett engines in Lear 30 and 50 series get spectrometric oil analysis programs (SOAP) and the Pratts in the 60 series don't.

It all depends on the engine service plan you enroll the engines on when you purchase the aircraft. The service plans require SOAP samples be taken at specific intervals (150-300 hours) to ascertain the "health" of the engine. Garrett engines are very reliable, but programs like MSP, JSSI, ESP, and others can specifiy the SOAP interval. This however is NOT a chapter 5 item and therefore is not a required maintenance task.

P&W has ESP (Eagle Service Plan) if I remember ( I maintained Lear 60-235) there were SOAPs required to be in the Gold ESP......but it's been a few years now. Pratt has issues brewing with the 300 series engines, such as the HPT blades eroding and not making hot section, and a rash of bad BOV's.
