18 Oct Hard Time Definition Aviation
One of the main areas of aviation growth over the past 12 months has been the “parts” or “aftermarket” industry, with an increasing number of assets demolished. We have received a number of requests from subscribers to discuss COMPONENTS in an aircraft at a high level.

This component can be modified during routine inspections, troubleshooting, or as part of an operator`s reliability program.

This includes maintaining components when they are removed from the aircraft, e.g. engines, APUs, seats. Sometimes this is done within the same organization as basic maintenance, but sometimes special companies do this work separately. This typically includes pre-flight checks, daily checks (before the first flight), troubleshooting, and smaller scheduled maintenance, as follows.
According to EASA Part 145, AMC 145.A.10, line maintenance is to be understood as “any maintenance performed before flight to ensure that the aircraft is fit for purpose”. This can include the following: If a component is in state or OC, it means that certain tasks are assigned to the component. It can be a function of the component itself or the system to which the component belongs during its installation on the aircraft. The requirements for OCCM components as well as HT components are largely determined by contract, so the “return” or “redelivery” conditions of the lease determine the requirements. Maintenance intervals are parameters specified in the Approved Maintenance Plan (AMS), which in turn is based on the Maintenance Planning Document (MPD). These are determined based on various criteria, usually based on how damage can be detected and the expected failure [CAA, 2017]: There are many reasons why a component can be changed during aircraft leasing, such as component failure, troubleshooting aircraft defects, or when the component reaches the end of its defined life. A component that is “HT” or “Hard Time” simply means that the component has a defined lifetime. It is usually counted in flight hours or airplane cycles (although these can be calendar days). The limit is usually set by a manufacturer (OEM), and at this limit, a defined action such as a review or bench test is required. This requirement is not affected by the function of the component or standard and is required regardless of the condition. No aircraft is so tolerant of negligence that it is safe without an effective inspection and maintenance program. The processes that affect an aircraft are deterioration with age (e.g., fatigue, wear and corrosion) as well as accidental failures (e.g., tire bursts, excessive structural loads).
For preventive work to be worthwhile, two conditions must generally be met: “Maintenance is the process by which a system is continuously performing its intended function at the expected level of reliability and safety.” [Kinnison and Siddiqui, 2013]. Aircraft maintenance can be defined in several ways, and the following can help to understand the different aspects: The components of the aircraft can be divided into two basic categories: Maintenance consists of a combination of preventive and corrective measures, including precautions to ensure that there have been no undetected accidental failures. There will be an inspection to monitor the progress of wear and tear processes, in addition to: Lease requirements are part of a “contract” and therefore it is important to review the lease and ensure that the replaced components meet leasing, regulatory and future requirements for the next lease of the aircraft.
