Narrative:

Issue: serious potential risk of engine failure on the cirrus SR22T post continental service bulletin (csb). Maintenance work by cirrus certified aircraft repair station X in ZZZZ. After a cirrus ballistic recovery system (brs) [parachute] incident in USA; continental [engines] issued csb 15-7A to replace an oil cooler cross fitting; since one had fractured in the USA incident resulting in a total engine failure. The replacement part from continental was replaced by aircraft repair station X in november 2015 at ZZZZ where the plane was in a hangar. On a flight four days later from ZZZZ to ZZZZ1; I flew at F210 and flight time was 1-hour 10-minutes with most of the flight at night. Night landing. After landing I noticed a significant oil leak with oil on the underside of the aircraft and on the bottom six inches of the tail. Repair station X engineer visited the plane and found that the [oil cooler cross fitting] replacement part was loose and leaking; this being the cause of the oil leak. On landing my oil level had gone from six to two. Repair station X say the leak was just seepage and the oil was 5.5 when the engine was cold. This is not correct. The continental service bulletin (csb) says that the part cannot be retightened which is what they have done.discussions with cirrus representative from cirrus USA and representative from continental engines have advised me that the failure was with aircraft repair station X not installing the replacement part correctly and according to the csb. They did not want to make any changes and after my demands to replace all the components they have now agreed to do so. Both continental and cirrus have confirmed that I was very likely to have had a total engine failure with a brs [parachute] pull or emergency landing at night if flight had continued for longer. Overall this was a major failure post workshop; for a csb that failed. Repair station X denies any failures and do not want this episode reported. I am concerned that another cirrus SR22T aircraft will have a failure and an emergency landing.

Title: Pilot of a Cirrus SR22T aircraft reports about the improper maintenance practices of a certified Aircraft Repair Station that contributed to an excessive oil loss from his Continental IO-550-K Engine. Repair Station had twice failed to follow procedures in Continental Service Bulletin (CSB) 15-7A for replacement of an Inter Cooler; oil cooler cross fitting.
