## The airworthiness directive

80-18-51 SOCIETE NATIONALE INDUSTRIELLE AEROSPATIALE: Amendment 39- 4143. Applies to Model SA-330 series helicopters, certificated in all categories.

Compliance required as indicated.

To prevent friction between the electrical wires and hydraulic lines, which could result in leakage of hydraulic fluid and possible fire, accomplish the following:

Prior to further flight, unless already accomplished within the last 50 hours time in service, inspect the electrical wires and hydraulic lines between fuselage stations 5295 and 5600 for chafing against each other and the airframe, and separate and secure electrical wires and hydraulic lines as necessary to prevent chafing. Any chafed electrical wires or hydraulic lines must be replaced before further flight. Report defects found to the Chief, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, FAA, c/o American Embassy, Brussels, Belgium. (Reporting approved by the Office of Management and Budget under OMB No. 04- R0174.)
