REGULATORY TEXT:  
76-19-06 SOCIETE NATIONALE INDUSTRIELLE AEROSPATIALE (formerly SUD AVIATION: Amendment 39-2729. Applies to "Puma" Model SA-330F and SA-330G Helicopters incorporating main rotor blades P/N 330.A11.00.12 (all issues), certificated in all categories.

Compliance is required as indicated, unless already accomplished.

To prevent cracks in the spars of the main rotor blade and possible blade failure, accomplish the following:

(a) Within the next 10 hours time in service after the effective date of this AD, install operating limitation placards on the instrument panel in full view of the pilot, setting forth the limitations specified in paragraphs (a)(1), (a)(2), and (a)(3) of this paragraph.

(1) Collective Pitch Limitations: For gross weights between 14,800 and 15,400 pounds, do not exceed 13 degrees. For gross weights between 13,200 and 14,800 pounds, do not exceed 13.5 degrees at or below 6600 feet density altitude, and do not exceed 14 degrees when above 6600 feet density altitude. For gross weights below 13,200 pounds, do not exceed 14 degrees.

(2) Airspeed Limitation: During descent, do not exceed 105% of the airspeed attained in level flight with the limit collective pitch of paragraph (a)(1) of this paragraph.

(3) The collective pitch and airspeed limitations of paragraphs (a)(1) and (a)(2) of this paragraph do not apply to operations without cargo or passengers and with minimum required flight crew, provided no main rotor blade has accumulated more than 400 hours time in service since new.

(b) Inspect the blade inspection method (B.I.M.) indicators of each main rotor blade, with the rotor stopped, at the following intervals:

(1) For rotorcraft used in operations involving 4 or fewer landings per hour, inspect within 3.5 hours time in service after the effective date of this AD and thereafter continue to inspect at intervals not to exceed 3.5 hours time in service from the last inspection.

(2) For rotorcraft used in operations involving more than 4 landings per hour, inspect within 1.5 hours time in service after the effective date of this AD and thereafter continue to inspect at intervals not to exceed 1.5 hours time in service from the last inspection.

(c) If, as a result of any inspection required by paragraph (b) of this AD, the color of the B.I.M. indicator is red, replace the blade with a serviceable blade of the same part number prior to further flight.

This amendment becomes effective October 4, 1976.
