Unsafe Condition
Leakage of flammable fluids from flexible hose assemblies in the engine compartment due to potential failure of Aeroquip 601 series or Stratoflex 156 series hoses.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect fuel lines by pressurizing with boost pump in high position and mixture control in idle cutoff, examine for fuel stains or leakage; inspect oil lines for wetness or leakage. Replace hoses if leakage is found. Inspections are no longer required once hoses are replaced with Bellanca or TSO-C53a identified assemblies.

ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 72-01-01 BELLANCA: Amendment 39-1367. Applies to following airplanes: Models Serial Numbers Affected 14-19-2 4001 thru 4105 14-19-3 4106 thru 4228 14-19-3A 4229 thru 4342 17-30 30001 thru 30262 Compliance: Required as indicated unless already accomplished. To detect leakage of flammable fluids from flexible hose assemblies in the engine compartment within 50 hour's time in service after the effective date of this AD and thereafter at intervals not to exceed 100 hours' time in service, accomplish the following: A) Visually, or by any other method approved by FAA, inspect fuel lines as follows: 1. Pressurize the fuel lines with boost pump operating in high position. When accomplishing this test, the mixture control must be in the idle cutoff position. 2. With fuel lines pressurized, examine all flexible hose exteriors in the engine compartment for evidence of fuel stains, wetness or leakage. 3. After pressure testing fuel hoses, allow sufficient time for excess fuel to drain overboard from the engine manifold before attempting an engine start. B) Visually, or by any other method approved by the FAA, inspect oil lines for evidence of wetness or leakage. C) If, as a result of the inspections required by Paragraphs A or B, fuel or oil stains, wetness or leaking is found, replace with a serviceable hose assembly. D) Inspections required by Paragraphs A and B will no longer be required when hose assemblies are replaced with assemblies identified by either a Bellanca metal identification band or a TSO-C53a Type C identification band. (This does not preclude continued inspections of this area as required by FAR 91.) NOTE: The airplane models listed above use either Aeroquip 601 series or Stratoflex 156 series flexible fluid hoses in their engine compartments. These hose assemblies are available under Bellanca 198003-x series part numbers. This amendment becomes effective December 31, 1971. FOOTER:
