Comprehensive Systems & Equipment Breakdown

This catalog provides exhaustive coverage across critical airframe sub-systems. In Chapter 21, the environmental systems are detailed from the exhaust heat shroud manifolds and nacelle dump valves through to cabin distribution tees, mixing boxes, and push-pull control cables. Chapter 22 delivers complete support for both Century IIB and Century III flight control systems, including directional gyros, attitude gyros, radio couplers, amplifier consoles, and the mechanical bridal cable clamps connecting servos to aircraft control runs. Chapter 23 outlines multiple factory avionics configurations, detailing mounting trays, antenna coax leads, and harness connectors for Narco, Collins, and King avionics suites, along with emergency locator transmitters. Electrical generation in Chapter 24 is thoroughly documented with battery box venting, master relay connections, 60-amp alternator brackets, diode heat sinks, and auxiliary ground power receptacles. Interior seating in Chapter 25 is broken down to individual frame weldments, release pins, slide tubes, cushion upholstery, and safety belt inertia reels.

Grumman Part Numbering & Hardware Identification

A distinctive feature of this publication is Section I, which decodes the specialized Grumman American part-numbering system. Technicians can immediately identify part classifications by prefix and suffix codes, distinguishing machined components (M), castings (C), forgings (F), plastic mouldings (P), honeycomb panels (H), and service kits (SB). In addition, Section II provides a massive alpha-numerical cross-index linking standard AN, MS, and NAS aircraft hardware—including structural rivets, castellated nuts, clevis pins, Adel clamps, and O-rings—directly to their respective catalog figures and system installations. A dedicated H4 Federal Supply Code index gives the names and addresses of original component manufacturers, providing invaluable assistance when researching supplier certifications.
