What to do
Owners, operators, and maintenance personnel should inspect for interference between the oil filter housing and oil cooler hose assembly at the next oil change or sooner. If interference is found, reposition the hose assembly to ensure at least 0.125 inches of clearance or follow manufacturer guidance before further flight. Any unsatisfactory conditions must be corrected, and a Malfunction or Defect Report or Service Difficulty Report should be filed with the FAA.
Summary
The Special Airworthiness Information Bulletin SAIB: CE-11-37 is an FAA informational bulletin addressing engine oil filter interference issues in Piper PA-44-180 aircraft with Lycoming O-360-A1H6 and LO-360-A1H6 engines, and Cessna 172R and S aircraft with Lycoming IO-360-L2A engines. The bulletin highlights potential interference between oil cooler hose fittings and the oil filter that could lead to improper installation and oil system problems. Other engines and aircraft models may also be affected.
What changed
This bulletin introduces awareness of a potential interference issue between oil cooler hose fittings and oil filters on specified Piper and Cessna aircraft models. It does not mandate corrective action but provides recommendations to inspect and correct any interference found during maintenance. The bulletin clarifies that this issue is not currently considered an unsafe condition requiring an Airworthiness Directive.
Why it matters
This information is important for operators, maintenance personnel, and compliance teams because improper oil filter installation due to interference can cause oil loss and loss of oil pressure, potentially leading to engine damage. Early detection and correction help maintain engine reliability and safety. Understanding this issue helps avoid unexpected maintenance problems and supports continued airworthiness.
