Electrical systems are tested, and all instruments are calibrated. Any discrepancies are documented and corrected. The mechanic utilizes STCs and Cessna Service Kits (like SK172-60A) as needed, ensuring adherence to all applicable regulations.
Progressive Inspection Program
The Cessna 152 maintenance manual supports a Progressive Inspection Program, allowing for a more distributed workload compared to solely relying on annual inspections. This involves breaking down the annual inspection tasks into smaller, more frequent checks throughout the year.
These progressive inspections, guided by the manual, can be scheduled based on flight hours or calendar time. Common tasks include detailed engine oil analysis, flight control rigging checks, and thorough electrical system assessments.
This approach minimizes downtime and spreads maintenance costs, enhancing aircraft availability. Proper documentation of each progressive inspection is vital, contributing to a comprehensive maintenance history and ensuring continued airworthiness.
Essential Maintenance Tasks
The Cessna 152 maintenance manual details crucial tasks like oil changes, spark plug replacements, tire upkeep, and battery inspections for optimal performance.
Oil Changes and Filter Replacements
Regular oil changes are paramount for Cessna 152 engine longevity, as detailed in the maintenance manual. The frequency depends on operating conditions, but typically occurs every 50 flight hours or annually, whichever comes first.
Utilize the oil grade specified by Cessna – often a multi-grade aviation oil – and always replace the oil filter concurrently with the oil change. Proper disposal of used oil is essential, adhering to environmental regulations;
The manual outlines specific torque values for the drain plug and filter to prevent leaks. Thoroughly inspect the oil screen during each change for any metallic debris, indicating potential engine wear. Consistent adherence to this schedule, guided by the Cessna 152 manual, ensures reliable engine operation.
Spark Plug Inspection and Replacement
The Cessna 152 maintenance manual dictates a schedule for spark plug inspection, typically during the 100-hour or annual inspection. Inspect electrodes for wear, fouling, and proper gap settings, referencing the manual’s specifications.
Spark plug replacement is crucial for maintaining optimal engine performance. Use only Cessna-approved spark plugs, ensuring correct heat range and thread reach. Torque the plugs to the specified value to prevent damage to the cylinder head.
Carefully examine the removed plugs for signs of engine issues – oil fouling, lead deposits, or overheating. Document all findings in the aircraft’s logbook. Following the manual’s guidance ensures efficient combustion and prevents potential engine malfunctions.
Tire Maintenance and Pressure Checks
The Cessna 152 maintenance manual emphasizes regular tire inspections for wear, damage, and proper inflation. Check tire pressure before each flight, adhering strictly to the recommended values specified in the Pilot Operating Handbook (POH) and the maintenance manual.
Inspect tires for cuts, bulges, and uneven wear patterns. Look for brake fluid contamination, which can degrade the rubber. Ensure proper valve stem condition and security. Rotate tires periodically to promote even wear.
Document all tire pressure checks and any observed issues in the aircraft’s logbook; Maintaining correct tire pressure is vital for safe ground handling, braking performance, and preventing premature tire failure. Adherence to the manual’s guidelines is paramount.
Battery Inspection and Maintenance
The Cessna 152 maintenance manual details crucial battery checks. Regularly inspect the battery for corrosion around terminals, ensuring they are clean and tight. Check electrolyte levels (if applicable) and add distilled water as needed, following the manual’s instructions carefully.
Verify the battery’s charge state using a voltmeter. A fully charged battery is essential for reliable starting. Inspect battery cables for fraying or damage, replacing them if necessary. Proper ventilation around the battery is vital to prevent hydrogen gas buildup.
Document all battery inspections and maintenance actions in the aircraft’s logbook. Consistent battery maintenance, as outlined in the manual, ensures dependable electrical system operation and prevents unexpected failures.
Fluid Level Checks
The Cessna 152 maintenance manual emphasizes regular checks of engine oil, hydraulic, and brake fluids to guarantee optimal aircraft performance and safety.
Checking Engine Oil Level
According to the Cessna 152 maintenance manual, verifying the engine oil level is a critical pre-flight and routine maintenance task. This ensures adequate lubrication, preventing engine damage and maximizing its lifespan. The procedure involves parking the aircraft on level ground and allowing the oil to settle for several minutes.
Remove the oil dipstick, wipe it clean, reinsert it fully, and then remove it again to read the oil level. The oil level should fall within the “MIN” and “MAX” marks on the dipstick. Low oil levels necessitate immediate attention and topping off with the correct grade of oil, as specified in the manual. Consistent monitoring and documentation of oil consumption are also vital for identifying potential issues.
Regular oil level checks contribute significantly to the overall health and reliability of the Cessna 152 engine.
Hydraulic Fluid Level Inspection
