Certification basis CAR 6 dated December 20, 1956, including Amendments 6-1 through 6-7.
Type Certificate H5WE issued June 30, 1966.
Date of Application of Type Certificate July 15, 1964.
Production basis Production Certificate No. 600.
Equipment The basic required equipment as pr escribed in the applicable airworthiness
regulations (see Certification Basis) must be installed in the helicopter for
certification. Lockheed Report 19208, Section IIA “Equipment List,” contains
a list of all required equipment that must be installed as well as optional
equipment installations approved by the FAA.
NOTE 1. Current weight and balance report including lisdt of equipment included in certificated empty weight,
and loading instructions, must be provided for each helicopter at the time of original airworthiness
certification and at all times thereafter (except in the case of operators having an approved weight
control system).
Fuel and oil capacities as indicated are total tank capacities over and above “Trapped Fuel and Oil.”
The indicated capacity of the fuel tank does not include “Unusable” fuel of 10 pounds which cannot
be used safely in all flight attitudes, a nd which must be included in the empty weight.
NOTE 2. The following placard must be installed in the Pilot’s Checklist:
“This helicopter must be operated in compliance with the operating limitations specified in the FAA
Approved Rotorcraft Flight Manual.”
For additional placards, see FAA Approved Rotorcraft Flight Manual.

NOTE 3. The retirement times of critical parts are lis ted in the following table. These values of
retirement or service life cannot be in creased without FAA Engineering Approval.
Life limited components removed when life limit has been reached must be destroyed or
permanently marked to prevent return to service.
