Cessna 210 Prebuy Examination—Scope and Detail

NOTE: This is a two-phase checklist. Please perform “Phase 1” items first and report results before proceeding with “Phase 2” items. If there are any high-cost issues noted during Phase 1, we may need to terminate the prebuy examination early.

NOTE: Estimated labor hours to complete both phases of this checklist: 10 – 15 hours depending on equipment installed.

PHASE 1

1.1 Operational and Functional Check

1.1.1 Perform “Airplane Operational and Functional Check run-up”.

1.2 Engine and Propeller

1.2.1 Check cylinder compressions hot. Report compression readings, master orifice reading, and location of audible air leakage (rings, exhaust valve).

1.2.2 Check cylinder heads for cracks, with concentration on the area between the fuel injector nozzle boss and the top spark plug boss. If a suspected crack is found, verify with dye penetrant and please provide a high- resolution photograph of the results.

1.2.3 Check pushrod housing seals, cylinder bases, and rocker covers for oil leaks.

1.2.4 Borescope examination of all cylinders. For each cylinder, report appearance of exhaust valve (particularly asymmetric appearance indicating hot spots), and appearance of barrel (loss of crosshatch, vertical scoring, aluminum smearing at 3 or 9 o’clock position suggesting piston pin plug scuffing, excessive oil in combustion chamber).

1.2.5 Spark plug examination. Report any abnormal color or appearance, particularly with the top spark plugs.

1.2.6 Remove oil filter, cut open and inspect for metal. If significant metal is found, please provide one or more high-resolution photographs of filter media, check with a magnet to determine whether metal is ferrous or non-ferrous, and save filter media in a zip-lock plastic bag in the event we need to send it out to a lab for microscopic examination.

1.2.7 Check crankcase for cracks and oil leaks. Check front crankshaft seal for oil leaks. If any cracks or leaks are found, please provide high-resolution photographs.

1.2.8 Check all fuel and oil lines, wire bundles and ignition harness leads for chafing and security. Check engine transducers (CHT, EGT, etc.) for lead chafing at strain-relief springs. Check all Molex connectors to ensure that they have blue weather seals.

1.2.9 Check engine baffles for cracks, particularly the side baffles. Check inter-cylinder baffles for proper position. Check flexible baffle seals for condition and proper orientation.

1.2.10 Check engine mount for corrosion, heat signatures, and damage to paint or powder coating.

1.2.11 Inspect exhaust system for leaks, cracks, bulges.

1.2.12 Check propeller hub for cracks and leaks. Check prop blades for nicks, corrosion, areas of excessive filing. Check propeller spinner and spinner backplate for cracks. If electric heat, check operation.

1.2.13 Check cowling for damage and repairs.

1.3 Maintenance Records

1.3.1 Check for complete airframe, engine and propeller logbooks.

1.3.2 Provide AD compliance list. Report any applicable ADs for which compliance is not well-documented.

1.3.3 Provide SB compliance list. Report any applicable SBs for which compliance is not well-documented, and identify whether mandatory, recommended or optional.

1.3.4 Check for compliance with all Airworthiness Limitations in Section 4 of AMM. If applicable, check for compliance with Airworthiness Limitations in any installed STC’s.

1.3.5 Report any Airworthiness Limitations for which compliance is not well-documented.

1.3.6 Check for compliance with overhaul/replacement schedule in Section 5 of AMM, and report any items for which compliance with recommended overhaul/replacement times is not well-documented (ex. Magneto 500 hour inspection).

1.3.7 Verify date of most recent 91.411/91.413 biennial certifications (static system, altimeter/encoder, and transponder).

IMPORTANT: Please report your Phase 1 findings to Savvy and obtain authorization to proceed with Phase 2.

PHASE 2

2.1.12 Check main gear saddle and security of gear saddles and spacers.

2.1.13 Check for hydraulic leaks at main gear pivot leg retaining bolt.

2.1.14 Check for hydraulic leak at main gear swivel fitting.

2.1.15 Check condition of brake calipers for leaks and damage to brake line near brake disc.

2.2 Cabin

2.2.1 Check date of brake master hoses (if accessible) and brake master cylinder mount structure. Check master cylinders for leaks.

2.2.2 Check windows for security, evidence of water leakks, cracks or scratches etc.

2.2.3 Check all interior lights (including instrument lighting) for proper operation.

2.2.4 Check fuel quantity indicators for proper operation. (Functional checks only; please do not defuel the aircraft for this check.)

2.2.5 Check headliner for evidence of leaks at door or windows.

2.2.6 Remove ELT batteries and look for leaks and corrosion. Perform functional check.

2.2.7 Check fire extinguishers for proper weight or pressure.

2.3 Airframe / Wings / Flight controls

2.3.1 Check entire exterior of airframe for significant cosmetic flaws (e.g. cracks, missing or discolored paint). Inspect for hail damage on top surfaces.

2.3.2 Perform a general corrosion check.

2.3.3 Verify that all required placards are installed and legible.
