Maintenance testing is a test that is performed to either identify equipment problems, diagnose equipment problems, or confirm that repair measures have been effective. It can be performed at either the system level (e.g., the HVAC system), the equipment level (e.g., the blower in an HVAC line), or the component level (e.g., a control chip in the control box for the blower in the HVAC line).
Maintenance, and hence maintenance engineering, is increasing in importance due to rising amounts of equipment, systems, machineries and infrastructure. Since the Industrial Revolution , devices, equipment, machinery and structures have grown increasingly complex, requiring a host of personnel, vocations and related systems needed to maintain ...
[3] [4] The MRBR is based on the analysis performed using ATA "MSG-3 Operator/Manufacturer Scheduled Maintenance Development" document (MSG-3 is for Maintenance Steering Group – 3rd Task Force). [4] The MRBR is an approved set of aircraft initial maintenance requirements as prescribed by the Appendix H to para. 25.1529 of 14 CFR part 25 ...
In minimal maintenance concepts, there may be minimal or no I-level maintenance, a system known as two-level maintenance (O-level & D-level). A system deploying a typical I-level repair capability would be known as a three-level maintenance system (O-, I-, and D-level).
The Criticality Index is often used to determine the degree on condition monitoring on a given machine taking into account the machines purpose, redundancy (i.e. if the machine fails, is there a standby machine which can take over), cost of repair, downtime impacts, health, safety and environment issues and a number of other key factors. The ...
[2] The required tests include a set of knowledge tests, followed by a practical test, which includes an oral examination component, and which is administered by a Designated Mechanic Examiner (DME). A person who fulfills the necessary requirements is issued a mechanic certificate with either an airframe or powerplant rating, or both. [3]
The key factor as to when and why this work is being done is timing, and involves a service, resource or facility being unavailable. [18] [19] By contrast, condition-based maintenance is not directly based on equipment age. Planned maintenance is preplanned, and can be date-based, based on equipment running hours, or on distance travelled.
An Airbus A321 from Iberia having its CFM56 changed. Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair.
