Incident at SAINT JOHN NB (CYSJ)
2015-07-21: UPDATE: TSB Report#A15A0037: The Moncton Flight College Piper PA44 (registration C-FXKN) aeroplane was on a round robin cross country flight from Moncton - Halifax - St John - Moncton. On departure out of St John (CYSJ), the pilot noted an oil leak. The crew requested return to the field but were told they may have to hold for traffic. They declared an emergency and proceeded to the field for landing. The engine was not shut down on the return. Maintenance found that the oil dipstick was not properly seated and some internal threads on the dipstick assembly were damaged. Four quarts of oil remained which was well within engine operating limits , however it was one quart below Moncton Flight College?s SOPs. The oil tube and dipstick assembly were replaced and the aircraft was returned to service.
2015-07-20: Update from Maintenance and Manufacturing: Maintenance found the left engine oil dipstick was sitting off of its seal and allowing oil for blow by the seal. The threads on the cap were allowing the assembly to only be threaded part way into the crankcase. This gave the feel to the pilot as if it was in and tight, but given the location, you could only see that the dipstick seal was not contacting the surface to provide a positive seal with the cowling off. A serviceable dip stick was installed and it screwed in perfectly. The engine and cowling was cleaned and a ground run perform to verify for leaks, non found, aircraft was released.
