Required equipment The basic required equipment, as prescribed in the applicable airworthiness regulations
(see the Certification Basis), must be installed in the aircraft for certification. Lockheed
Report No. ER-4425, for the Model 1329-23 series or Report LG76ER0162 for the
Model 1329-25 "Master Equipment List, Model 1329," contains a list of all required
equipment that must be installed, as well as optional equipment installations approved by
FAA. Required and optional equipment for individual aircraft will be specified in the
JetStar Handbook of Weight and Balance Data.
Service information The Lockheed Model 1329 operations and maintenance instructions, service bulletins,
and other service information, when FAA approved, will carry a statement to that effect.
NOTE 1. (a) Current weight and balance report including list of equipment included in certificated empty weight,
and loading instructions must be in each aircraft at the time of original certification and at all times
thereafter except in the case of operators having an approved weight control system. Approved
weight and balance data is contained in the Jet Star Handbook of Weight and Balance Data.
(b) The airplane must be loaded so that the (zero fuel weight) c.g. is within the specified limits at all times
(reference c.g. range).
(c) The weight of system fuel and oil as defined below, and hydraulic fluid, must be included in the
airplane empty weight.
System fuel: The weight of all fuel required to fill all lines and tanks up to the zero fuel point on the
fuel gauges in level flight attitude (3 degrees and 30 minutes nose-up). This includes the unusable
fuel as defined by CAR 4b.416.

Lockheed Report ER-5500M, revised February 2, 1962.
Zero fuel weight of 24,500 lbs. approved when interior modifications conform to the criteria of
Lockheed Report ER-5500M, revised August 15, 1963, and when structural modifications are
incorporated in accordance with Lock heed Service Bulletin No. 329-138 dated August 30, 1963.
Zero fuel weight may be increased to 25,000 lbs. after incorporation of the provisions of Lockheed
Service Bulletin No. 329-138B dated December 1965 for the Model 1329-23 series airplanes.
Zero fuel weight of 27,500 lbs. approved when interior modifications conform to the criteria of
Lockheed Report ER-5500M-II, revised February 8, 1977, for the Model 1329-25 series airplanes.
(e) Fuel loading and usage procedures are dictated by structural design, and to maintain airplane c.g.
within approved limits.
Refer to FAA approved Airplane Flight Manual for take-off, landing, and normal fuel distribution
limitations, normal fuel system management, and fuel system malfunction procedures.
Fuel must be loaded symmetrically about the airplane centerline.
Any landing with more than 500 lbs.* of fuel in either external tank must be considered an
overweight landing and an overweight landing inspection must be accomplished.
*2,250 lbs., S/N 5066 and up, and lower S/Ns incorporating JetStar Service Bulletin No. 329-157.
This limitation also applies to S/N 5201 and up.
(f) Fuel jettison capability must be available for operation of the airplane in excess of the maximum
landing weight. The unjettisonable fuel must be included in the airplane landing weight. The amount
of usable fuel remaining in the tanks after complete jettisoning is as follows:
Tanks 1, 2, 3, and 4: 1,000 lbs. each,
Total 4,000 lbs.
External tanks: None
NOTE 2. Placards and markings must be in accordance with Lockheed Drawing JG 387, for the Model 1329-25.
NOTE 3. All replacement seats (crew, passenger, and l ounge seats), although they may comply with TSO-C39, must
also be demonstrated to comply with CAR 4b.358(c). Other installations, such as berths, buffets, and
compartments or items of mass which could create a hazard to the safety of passengers and crew, must also
be demonstrated to meet the same requirements.

NOTE 4. The basic model number of the aircraft is 1329. The nameplate contains two sets of additional numbers, the
first set represents the engine and the second set represents the type of interior on initial issue of the standard
airworthiness certificate.
Examples:
1. 1329-23A-000 contains JT12A-6 engines and is a two-pl ace aircraft with no interior.
2. 1329-23A-001 contains JT12A-6 engines and is a ten-pl ace aircraft with a Lockheed standard interior.
3. 1329-23D-000 contains JT12A-6A engines and is a two-pl ace aircraft with no interior.
4. 1329-23E-00 contains JT12A-8 engines and is a two-pl ace aircraft with no interior.
5. 13329-25 contains TFE731-3 engines and is a two-pl ace aircraft with no interior.
NOTE 5. Main tank fuel boost pumps, Lockheed P/Ns JP 1000-5 or -8, Lear P/Ns RR 12040B or RR12040E, must be
removed from the aircraft and returned to the pump manufacturer for inspection after each 300 hours of
flying time in accordance with Lockheed Service Letter 329-2035. When main tank fuel boost pumps,
Lockheed P/Ns JP 1000-7 or -9, Lear P/Ns RR 12040D or RR 12040F, are installed, the approved time
between overhaul is 2000 hours.
NOTE 6. Approved engines are eligible with or without Pratt and Whitney change EC110181 (Aves kit) for the Model
1329-23 series airplanes.
NOTE 7. (a) JT12A-6 and JT12A-6 engines may be intermixed on all Model 1329 aircraft, provided the engine
limits and performance data for the JT12A-6 engine are used for all engines.
(b) The JT12A-6 engine is eligible for use on S/Ns 5001 through 5092 and 5094 through 5096.
(c) The JT12A-6A engine is eligible for use on S/Ns 5001 through 5045 at the power and temperature
limits of the JT12A-6.
(d) The TJ12A-6A engine is eligible for use on S/Ns 5001 through 5045 at the power and temperature
limits of the JT12A-6A after incorporation of JetStar Service Bulletin 329-147A dated April 17, 1964.
(e) The JT12A-6A engines are eligible for use on S/Ns 5046 through 5092, 5094 through 5096, and 5121.
