My N reg Cessna180 manufacturers recommended min check is 100 hrs
and the engine manufacturer might say oil change every 25 hours or 4 months.
Not even the basic LAMP/LAMS checklist every 50 hours or 6 months really satisfied the recommendation for a 4 month oil change.
Part 145 and Subpart F organisations have additional new privileges
Timelines:
For ELA1 aircraft, the changes came into effect on the 27 July 2015, and a template for the new AMP options described above is now available.
Which means that all Part 145 and Part M Subpart F organisations will have to read and understand the new rules, alter their manuals, submit the manuals to CAA or LBA etc. Expect to wait a few months before any maintenance organisations can implement this.
Hopefully less paperwork will mean more time for maintenance, not less maintenance.
