Line Maintenance vs Base Maintenance – Detailed Guide

 Aircraft maintenance is divided into two main categories: line maintenance and base maintenance. Both are essential for aircraft safety and efficiency.

Line Maintenance:

Performed at the airport between flights

Includes pre-flight checks, minor repairs, fluid inspections, and tire pressure checks

Ensures aircraft is ready for the next flight

Base Maintenance:

Performed in a hangar, takes longer time

Includes major repairs, engine removal, structural inspection, and replacement of critical components

Aircraft may stay in base maintenance for days or weeks

Key Difference:

Line = quick, small tasks

Base = detailed, extensive tasks

Safety Tips:

Always follow manufacturer’s guidelines

Ensure proper PPE and tools are used

Report any issues immediately

 Top 10 Mechanical Safety Practices in Aircraft Maintenance Aircraft maintenance is a highly technical and safety-critical field. Mechanical safety ensures that both personnel and aircraft remain safe during maintenance tasks. Here are the top 10 mechanical safety practices every aviation technician should follow: 1. Wear Proper Personal Protective Equipment (PPE) Always use PPE including gloves, safety goggles, helmets, and protective footwear. PPE prevents injuries from sharp edges, chemicals, and moving parts. 2. Follow Lockout/Tagout Procedures Before working on hydraulic, electrical, or engine systems, ensure that power sources are properly locked and tagged. This prevents accidental activation of equipment. 3. Inspect Tools and Equipment Check all tools, jacks, lifts, and machinery before use. Damaged or uncalibrated tools can cause accidents and compromise maintenance quality. 4. Secure Aircraft Before Maintenance Use wheel chocks, landing gear locks, and tie-downs to ensure...

Aircraft Landing Gear – Types, Parts and Working (Complete Guide)

Image
 Aircraft Landing Gear – Types, Parts and Working (Complete Guide) Introduction Aircraft landing gear is one of the most important systems of an aircraft. It supports the aircraft during landing, takeoff, and taxiing. The landing gear absorbs shock during landing and provides stability while the aircraft is on the ground. Without landing gear, safe landing and ground movement would not be possible. What is Aircraft Landing Gear? Aircraft landing gear is a structural system that includes wheels, shock absorbers, brakes, and supporting structures. It helps the aircraft to: Land safely Taxi on runway Park on ground Absorb landing impact Main Parts of Aircraft Landing Gear 1️⃣ Shock Strut (Oleo Strut) Absorbs landing impact using hydraulic fluid and compressed air. 2️⃣ Wheels and Tires Support aircraft weight and allow movement on runway. 3️⃣ Braking System Helps slow down aircraft during landing. 4️⃣ Retraction Mechanism Used in retractable landing gear to fold wheels inside aircraft ...
