Unsafe Condition
Failure of the oil pressure gauge hose assembly P/N B7071 without a 'T' stamped on the wrenching flats could result in loss of engine oil and possible engine failure.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Visually inspect the oil pressure gauge hose assembly to determine if it is P/N B7071. If the assembly matches Figure 1, replace it with a new P/N B7071 hose assembly stamped with a 'T' on the wrenching flats before the next flight. Equivalent compliance may be approved by the FAA.
