Level 1 Repair

[Kum Verna]

ALevel of Repair Analysis is a method of analyzing systems or machinery to minimize the money and time you spend on maintenance. The outcome of a LORA gives you tactics to return the machinery to a serviceable state while reducing its overall life-cycle costs.

In aviation, line maintenance occurs at the gate once an aircraft taxis in. Technicians quickly replace failed components, fix broken seats, or change worn tires before the aircraft leaves to its next destination.

Known as I-level maintenance, is a step up in the level of work done. I-level maintenance occurs in workshops with greater tooling and diagnostic equipment. Maintenance durations are longer and use sub-components to return assets to a serviceable condition with permanent damage repairs.

An example is an aircraft due for a service or a maintenance check. It is towed to a nearby hangar to allow the work to be done overnight before returning to the gate the following day for its first departure.

Every few years, an aircraft will fly to a heavy maintenance base for a complete strip-down to its subcomponents, with these sent into the extensive overhaul shops attached to the maintenance hangar.

Before you can focus on cost, the facility to use, and the depth of repair capability required for a specific asset, you first need to understand how important is that asset to your operation, and what it takes to maintain its serviceability.

Changing the oil and cleaning the filter is within the capabilities of a mobile maintenance team using simple hand tools. The filters and seals have a short lead time, and the oil is a bulk purchase.

If the magnetic plug shows metal traces, the gearbox will need to be replaced with an overhauled item. This task requires a gearbox jack for safe removal, and a spare gearbox to be available, but it is still within the capabilities of a mobile maintenance team.

In our example of the PTO gearbox, you can cost the manhours and spares required for an oil change. Additional investment in tooling, skills, or maintenance facilities is not required, and the cost of holding inventory is negligible. Changing the gearbox will incur costs for training, the purchase of gearbox jacks, the capital cost of purchasing a spare gearbox, and the inventory-holding costs.

Overhauling the gearbox will require a large investment to upgrade your maintenance facility and purchase diagnostic and test equipment. You likely need to send technicians for additional training as overhauling these particular gearboxes is not a walk in the park.

If we are paid by the acre, an inability to operate severely affects monthly revenue and causes delayed start dates for subsequent customers. As the work is seasonal, the delayed operation will limit our annual earnings and upset our customers.

A CMMS becomes a central repository for capturing and reporting maintenance costs, tooling, resource availability, inventory insight, and turnaround times, greatly reducing your data collection requirements. Furthermore, CMMS automatically calculates failure rates and KPIs that provide input to optimization studies and scenario planning.

Once the LORA is complete and tactical maintenance decisions are taken, you can use CMMS to update maintenance schedules and ensure the correct routing of assets and sub-assemblies. You can also adjust inventory min/max levels to support the revised repair or maintenance decisions and update external supplier data.

A LORA is not a difficult process, but it does require rigor when considering all the levels and types of maintenance an asset requires. It also demands an understanding of asset criticality, maintenance costs, and facility capabilities.

On the other hand, it will make maintenance programs more efficient and effective, helping to standardize maintenance decisions and minimize costs while providing optimal asset uptime and serviceability.

That lovely camera you are seeing in the picture is the Nikon F with the standard eye-level finder. If this setup reminds you of the Vietnam war, then you are on the right track. This is the camera that photographed plenty of Vietnam war photographs. If you see pictures of war photographers in that era, big chances are they have one or more strung around their necks. The camera itself is not expensive but the finders usually cost multiple times more because finders with good prisms are not easy to find. You can fix one yourself, I will show your how once I source a reliable and cheap supplier.

Finally, we can remove the prism! Clean this brace properly and use electrical tape in place of the foam and make sure that the sticky part of the tape is facing away from the prism. If you used foam in this part again then it will corrode just like what happened previously.

Thanks, James! Be careful with the screw head, be sure you have the right width screwdriver that fits perfectly on the slot. I learned the hard way, these screws are old and some are brittle. You may also want to use your upper body weight on some nasty screws. Ric

Morgan Sparks at supplies superb adhesive-backed leatherette at very reasonable prices but the link to Nikon Fs is currently broken. I am awaiting a reply to my email to see if he still does Nikon leatherette.

Thanks, Pete!

I can only vouch for vendors that I had interacted with. Asahi Aki is more than what I need for this sort of thing. Have you checked him out? He has a bery good reputation locally and internationally as well as I recently found out. Ric.

Richard, though you wrote this article six years ago, and I am sure countless Nikon F owners have benefited from your ingenuity and sharing your experience. Thank you. May I suggest either a link to your article on Camera Leather Replacement or a short write up on reattaching the Nikon Leatherette without over-gluing and extruding it between the edges and the metal housing. So far, I have not found any suitable replacement glue at any of the warehouse-type pretend hardware stores, in Australia.

We can repair, restore, refurbish and calibrate all makes and models of precision levels. We work with companies throughout the United States and have close ties with local and national industrial supply companies, manufacturers and calibration laboratories, providing a "one-stop" solution to your repair needs. We maintain an expansive inventory of 100% factory replacement parts in our warehouse so express repairs are readily available.

We had a minor problem they came ahead of time, finished very fast. They were very professional and friendly. The cost was excellent for the job they did. I would recommend them again to all people who need structural repair.

After much anxiety about how much foundation repair would cost, I was very pleasantly surprised to learn how affordable Level Home Foundation Repair was. They were on time for both the initial appraisal & the actual repair work. They were pleasant, respectful, and did a great job on the leveling and clean up. They raised the house, with no cracks in the brick, no visible gap between the brick and wood facing. Great job overall. I would recommend them highly.

Great all around company!! I would definitely recommend using them to anyone in need of foundation repair. Customer service is off the charts, as well as their work!! Everything is guaranteed and transferable, if you ever look to sell your home.

Level of Repair Analysis (LORA) is used as an analytical methodology used to determine where an item will be replaced, repaired, or discarded based on cost considerations and operational readiness requirements. For a complex engineering system containing thousands of assemblies, sub-assemblies, components, organized into several levels of indenture and with a number of possible repair decisions, LORA seeks to determine an optimal provision of repair and maintenance facilities to minimize overall system life-cycle costs.

Logistics personnel examine not only the cost of the part to be replaced or repaired but all of the elements required to make sure the job is done correctly. This includes the skill level of personnel, support equipment required to perform the task, test equipment required to test the repaired product, and the facilities required to house the entire operation.

LORA establishes when and where each unit will be repaired and determines if it is more cost effective to discard an item than attempt to repair it. While this kind of analysis seems costly and unnecessary, at enterprise scales over many years, significant cost savings can be realized.[citation needed]

For example, the LORA process may discover that replacing a part actually costs hundreds of times that amount, when all cost are considered (maintenance manpower, warehousing facilities, shipping, etc.). If this part is replaced hundreds of times per year, over the course of many years, then there may be an opportunity to save money by adjusting the repair process to leverage this economy of scale (reliability improvements, component repair, etc.).

This analysis drives the maintenance support for each repairable unit analyzed. LORA is the most important physical supportability analysis business decision made during acquisition of a system.[why?]
