MODULE 1-GENERAL LABORATORY STANDARDS

• Aircraft maintenance facility - must provide excellent environments for the aircraft maintenance technicians to perform their extremely important work
• Aircraft hangars - are as ubiquitous to the aviation community as airplanes and aircraft themselves; if there are aircraft, it is reasonable to expect a hangar is close by
• Maintenance Hangars - are a vital piece of the maintenance, repair, and overhaul (MRO) chain of events
• MRO - Maintenance, Repair, And Overhaul
• Maintenance hangars - they are a much different entity than a line or storage hangar
• Traditional line hangars - have one primary function which is to house the aircraft safely and securely. They are not intended to be spacious or comfortable, but instead exist to house an airplane.
• Maintenance Hangars – they are used exclusively in the MRO arena, are broad, wide-open arenas with the sole purpose of conducting major repairs on aircraft
• Major Repair - is anything that requires the removal and installation of power plants and associated accessories, as well as major structural and airframe components
• Overhaul - includes major structural components as landing gear, flight controls and rigging, and systems repairs
• MRO hangars – they are not at every airport. They are pricey affairs, and they are not just installed to house and repair aircraft
• Base-Level Maintenance – a type of maintenance that is in associated maintenance stands, scaffolding, tools, test stands, and even component overhaul back shops (hydraulic and pneumatic system components, such as actuators and brakes, are overhauled for continued use)
• Line Maintenance - which is the general servicing and inspection of aircraft (changing tires and brakes, making minor repairs to dents and skin, etcetera).
• Aircraft jacks - attach to fixed hard points on the aircraft
• Kinds of Hangars:

  ·       Parking Hangars

  ·       Maintenance Hangars
• tailoring the building to the mission – the gold standard for MRO facilities
• Parking Hangars - have a single purpose: park as many airplanes inside as possible
• Parking Hangars - these facilities are intended to be built as a wide-open bay, and the operator is money ahead when they can fill it to the brim with static aircraft
• Maintenance Hangars - must be designed in such a way that necessary support equipment is available immediately, docked and stowed for service
• Maintenance Hangar - must be equipped with a parts hold or supply point, shipping and receiving on location
• GSE - Ground Support Equipment
• Example of GSE:

  ·       aircraft tugs

  ·       power carts

  ·       start carts

  ·       test stands
• Aircraft Tug - represents the epitome of usefulness and efficiency in the GSE stable
• AGV – Automated Guided Vehicles
• Automated Guided Vehicles (AGV) - are a tremendous advance for maintenance because now major structural components and engines can move safely through the facility completely autonomously with laser precision
• Human Error - shown to be the most prevalent source of damage and loss in ground operations
• Overhaul Components:

  • Major Structural Components
  • Landing Gear
  • Fligh Controls
  • Rigging
  • System Repairs
• Aircraft Hangar Safety Tips:

  • Staff Safety
  • Tool Use
  • Aircraft Protection
  • Hangar Organization
  • Equipment Maintenance
  • Procedures
• PPE - mandatory type of equipment that employees must use or

  wear to protect them from the risks in their work environment
• PPE - PERSONAL PROTECTIVE EQUIPMENT
• required equipment inspections:

  • daily
  • weekly
  • monthly
  • yearly
