Base Maintenance Operations and Hazards Maintenance hangars are very large structures capable of accommodating numerous aircraft. The largest hangars can simultaneously accommodate several wide-body aircraft, such as the Boeing 747. Separate work areas, or bays, are assigned to each aircraft undergoing maintenance. Specialized shops for the repair and refitting of components are associated with the hangars. Shop areas typically include sheet metal, interiors, hydraulics, plastics, wheels and brakes, electrical and avionics and emergency equipment. Separate welding areas, paint shops and non-destructive testing areas may be established. Parts-cleaning operations are likely to be found throughout the facility. Paint hangars with high ventilation rates for workplace air contaminant controls and environmental pollution protection should be available if painting or paint stripping is to be performed. Paint strippers often contain methylene chloride and corrosives, including hydr...

                          Maintenance work is divided between that which is necessary to maintain ongoing daily operations (line maintenance) and those procedures that periodically check, maintain and refurbish the aircraft (base maintenance).                 Line maintenance comprises en route (between landing and takeoff) and overnight maintenance. En route maintenance consists of operational checks and flight-essential repairs to address discrepancies noted during flight. These repairs are typically minor, such as replacing warning lights, tyres and avionic components, but may be as extensive as replacing an engine. Overnight maintenance is more extensive and includes making any repairs deferred during the day’s flights.                             The timing, distribution and nature of aircraft mainte...

Many airports have hidden dangers in places where flight crews and flight line technicians should be attentive. Warm weather conditions can cause insects, spiders, and reptiles to emerge in unexpected places. Caution should be utilized when performing a pre-flight walk-around, maintenance operations, or other duties. Taking a moment to look before you reach will help avoid painful stings, bites, and unexpected encounters. It is also wise to be aware of favorable habitats for insects, spiders, and snakes before extending your hand into dark corners or holes. A flashlight or reflective mirror can be used for this purpose. Bee Swarms -Honey bees have caused concern in some  due to their aggressive behavior and the uncanny ability bees have to nest almost anywhere. Flight crews and technicians should pay attention if bees are seen flying fast and straight into and out of any object or area. This behavior is an indication that a colony is nearby. Due to the ...

       It is required to inspect the aircraft more frequently for the signs of bird activity through the spring and into mid-summer. Some bird species such as the  Sparrow instinctively seek out nesting cavity locations safe from  predators.             Small hollow spaces offered by a parked airplane can seem like an ideal location for these nuisance birds to nest.             A bird nest left unchecked in an airplane can result in costly maintenance and damage. By blocking cooling airflow  the nesting materials can cause critical aircraft systems to overheat. Also a bird nest can interfere with flight control movements.             Starlings which are particularly known to be untidy nesters will use all sorts of trash-type debris that can collect moisture and introduce foreign objects into the airfoil and fuselage structures.  ...

         Ground Run is an important part of maintenance and it should carried out with proper procedure and follow all relevant instruction.  Approval  for an engine ground run must be obtained from airport.      Safety All personnel concerned with engine ground running must be fully conversant with  rules and with the following requirements, which must be complied with at all times.  The aircraft must be positioned correctly  in such a way that engine  running will not harm persons or cause damage to aircraft, buildings, installations,  vehicles or equipment in the vicinity. All apron equipment must be placed at a safe distance from the aircraft. Where applicable, the rear area must be closed, to safeguard vehicular  traffic.  The aircraft anti-collision beacon(s) must be switched on before engines are started and must remain on for the duration of the ground run. AME must ensure that th...

Electrical connector in cabin heater power supply  overheated                         (15 February 2012) During the approach, wisps of smoke were seen to  come from the area of the cabin heater selector switch.  The system was isolated, the cabin fire extinguisher  was discharged and the aircraft made an uneventful  landing. The source of the smoke and acrid smell was  an overheated and partially melted electrical connector. History of the flight An instructor was conducting an instrument training  flight with one student flying the aircraft and a  passenger, who was also a student, in a rear seat  observing the flight. The student had been given  clearance for a low approach and go-around. The  aircraft was approximately six miles from Birmingham  Airport, established on the ILS for Runway 33, when  the passenger reported that there were wisps of smoke...
