MRA Request Form

[Adam Sloon]

To All CC11 Owners:

The Owner Support section of the website now contains a document called the LSA Major Repair and/or Alteration (MRA) Request Form and can be found here. This document has been created to help handle the flow of change requests in a more timely and organized fashion. Our goal is to process the requests and return an approval/rejection with an estimate within 48 hours of submission.

The request form is designed to give us all the information we need in order to determine if the requested changes can be made on your aircraft, while still maintaining design and performance specifications. Information required in the form includes:

• Owner name and address
• Aircraft make, model, serial number, and N-number
• Airframe/Powerplant/Propeller manufacturer, type/model, serial number, total time since new, and total time since overhaul
• Current weight and balance
• Any previously installed MRA's, service instructions, etc.
• A copy of the current equipment list
• Requested changes

While many changes to an aircraft seem simple and may only require the minimum hour of work, others will require more research and time. Since changes and improvements to the manufactured aircraft are taking place on an ongoing basis, as well as the reality of aircraft equipment options, no two aircraft are exactly alike. With regards to MRA's, this means that a change that may be a simple remove and replace on one aircraft may involve modification of another, or may not even be possible.

One of the largest issues with modifications is staying under aircraft empty weight limits. By providing an MRA, we are vouching that these changes will still keep in the aircraft within LSA specifications. With so many aircraft being produced near the limits of empty weight, keep this in mind when considering a request.

The lower half of the form includes the estimate, approval, and payment options. The process for providing an MRA will be as follows:

1. Print MRA request form from website and fill out the entire first page
2. Send it to CubCrafters for evaluation
3. MRA is either denied or approved
   
   • Denied - Justification will be provided and owner/customer notified (end of process)
   • Approved - Hour/cost estimate will be determined (proceed below)
   
   
4. Estimate sent to customer for approval
5. Estimate accepted and payment made to CubCrafters
6. MRA will be put into queue and sent out to customer upon completion

Until we can get an interactive form on the website, feel free to email the first page's worth of information to CubCrafters, and we can fill the form out here and do the evaluation. Once the MRA is complete it will be mailed out, and a digital version will be emailed also if requested. You will also notice that hourly price has been set to $100.

There will be some instances where an MRA has already been performed and can basically be copied for future aircraft. In these cases, the minimum amount of time billed will be one hour ($100) to cover overhead costs. This means that the initial requester has to "eat the cost" of the work beyond one hour in creating the original MRA. The maintenance manuals for both the CC11-100 and CC11-160 provide approved instructions for many operations, and we plan to add as much of the basic maintenance processes as possible in order to limit the need for MRAs. Please understand that CubCrafters is not trying to make money off of MRAs, but is trying to recover costs in what is steadily becoming a larger portion of our responsibility as the manufacturer; fleet maintenance.

I apologize for the long post, but will continue to try and answer questions before they need to be asked. Feel to post any questions and comments. Thank you.

Just a quick question for clarification-

Does the process change at all if the airframe in question is certified E-LSA? Is the MRA process even required then?

John,

You do not need an MRA for an ELSA aircraft.

Once the Carbon Cub gets converted from SLSA to ELSA, the owner no longer requires manufacturer's approval for changes. The owner, however, is required to maintain the aircraft within the LSA specifications for gross weight, cruise speed, etc.

Is there any difference between an MRA and an LOA (letter of authorization)?

[Adam Sloon]

The MRA (Major Repair and/or Alteration) is basically just an updated version of an LOA. We used to issue LOA's which were more of a statement by CubCrafters approving changes. The MRA does the same thing, but now we are required to provide "written instructions and diagrams," the level of certification required to make the changes, and any testing procedures to verify the change. The MRA is CubCrafters signing off that the changes, according to the MRA, will not change the flight characteristics of the aircraft.
