Cessna 152 Parts FAQ: Sourcing, Fitment & Maintenance

Cessna 152 Parts Guide & Technical FAQ

The Cessna 152 is a two-seat, fixed-tricycle-gear general aviation trainer introduced for the 1978 model year and manufactured through 1985. Maintaining the Cessna 152 requires systematic part-number verification across structural, mechanical, powerplant, and electrical systems using the Cessna 152 Illustrated Parts Catalog (IPC) and applicable maintenance manuals.

Which engine powers the Cessna 152 and how are replacement engine parts identified?

Standard factory-produced Cessna 152 aircraft are equipped with the Lycoming O-235-L2C engine delivering 110 horsepower at 2,550 RPM, while later serial productions and specific service modifications utilize the Lycoming O-235-N2C variant. Powerplant components such as induction hoses, exhaust gaskets, spark plugs, magnetos, and Air Filters must be identified using the specific Lycoming O-235 parts catalog rather than the airframe manual alone. Always cross-reference the installed engine data plate, as field overhauls or Supplemental Type Certificates (STCs) may have altered the factory dash-number configuration.

How do I verify the correct part numbers for Cessna 152 airframe components?

Airframe parts must be selected using the Cessna 152 IPC specific to the aircraft serial number and production year. Structural components including control surfaces, hinges, fairings, and fuselage skins often had revisions introduced across the model run from 1978 to 1985, as well as distinct differences on the aerobat variant (A152). When sourcing structural or replacement hardware through American Aviation Parts, cross-reference the complete OEM part number, including any dash-number suffixes, before placing an order.

What electrical system voltage does the Cessna 152 use?

Unlike the earlier Cessna 150 series, which primarily utilized a 14-volt electrical bus, the Cessna 152 features a 28-volt direct-current electrical system. Belt-driven Alternators, voltage regulators, starter motors, panel lamps, and relays must be rated for 28-volt operation unless a documented modification has altered the electrical architecture. Verifying system voltage against the aircraft equipment list prevents damaging sensitive electrical components during replacement.

What specifications apply to Cessna 152 wheels, tires, and brakes?

Standard Cessna 152 models utilize a Cleveland 5.00-5 main wheel and brake assembly alongside a 5.00-5 nose gear assembly. Technicians and owners sourcing Aviation Tires must confirm ply ratings specified in the aircraft maintenance manual, typically 4-ply or 6-ply 5.00-5 aircraft tires. For brake overhauls, high-wear components such as the Brake Disc Aps 164-06406 or standard Cleveland wear plates must meet manufacturer thickness tolerances documented in the applicable component maintenance manual.

Can standard general aviation flight instruments be installed in a Cessna 152?

The standard Cessna 152 panel accommodates standard 3-1/8-inch instrument cutouts for primary flight instruments. Replacement units such as mechanical or pneumatic Altimeters and pitot-static Airspeed Indicators must feature range markings that conform strictly to the Cessna 152 Pilot’s Operating Handbook (POH) and FAA Type Certificate Data Sheet (TCDS) 3A19. Replacement attitude gyros and directional indicators must be verified for compatibility with the aircraft’s central vacuum system capacity and plumbing diameter.

Are FAA PMA parts authorized for use on the Cessna 152?

Parts Manufacturer Approval (PMA) components are fully legal for installation on type-certificated aircraft when the PMA supplement specifically lists Cessna 152 model applicability. Many routine replacement items—such as engine shock mounts, control cables, brake linings, and hardware—are commonly supplied under FAA PMA. The installing A&P mechanic or IA must verify that the PMA approval documentation explicitly covers the specific airframe model and serial number before signing the maintenance record entry.

What considerations apply when upgrading Cessna 152 avionics?

Modern communication, navigation, and transponder upgrades for the Cessna 152 require attention to structural tray mounting space, 28-volt wiring runs, and antenna placement. Upgrading aircraft Avionics often involves replacing legacy 1-inch to 3-inch radio stacks with integrated GPS/comm units or modern audio panels. Always ensure the accompanying installation kit, mounting trays, and coaxial cabling meet the technical data requirements specified in the STC or manufacturer installation manual.

What documentation should accompany Cessna 152 replacement parts?

Traceability documentation depends on the nature and regulatory status of the component. Certified replacement parts sourced from American Aviation Parts should be accompanied by appropriate manufacturer Certificates of Conformity (CoC), FAA Form 8130-3 airworthiness approval tags, or PMA documentation where applicable. The installing technician must retain these records in accordance with 14 CFR Part 43 and Part 91 to substantiate the airworthiness and traceability of the installed component.
