Experimental Aircraft Insurance When Someone Else Performs the Ground Run

You have arranged for a mechanic an experienced pilot or another builder to perform an engine ground run on your experimental aircraft. The person may know the equipment well, but insurance needs a separate review of the proposed activity and role. Permission from the owner does not by itself establish the protection available to everyone involved.

The central question is what changes when someone other than the builder operates the aircraft during testing. Identify that person, the work and the policy provisions before the run. At BWI, we help owners organize these details for a focused coverage request. Get an aircraft insurance quote from BWI and explain that another person will perform the ground run.

Describe the Other Person Role Precisely

Start with what the person will actually do. Operating the engine controls, supervising a builder, observing instruments and performing maintenance are different roles. If the person will also taxi or later test fly, disclose those additional activities separately.

Identify whether the person acts independently, as an employee of a shop or through another business. Provide the exact legal name of the business where relevant. A description such as my mechanic may be familiar to you but insufficient to explain the contractual and insurance relationships.

Also explain whether payment or another agreement is involved. Compensation does not automatically settle the coverage question, but it helps the reviewer understand the activity. The goal is an accurate description rather than a label chosen because it sounds less commercial.

Separate Permission Qualifications and Insured Status

There are at least three questions to answer. Does the owner authorize the person? Does the person satisfy applicable operational and policy conditions? What protection does the person have under the relevant insurance? A yes to one should not be presented as a yes to all three.

Provide the experience or qualifications requested for the review. Do not assume that flight experience is the only relevant information or that an engine run never raises a pilot provision question. Ask the reviewer to identify the provisions that apply to the stated activity.

Finally, ask whose liability the proposed arrangement addresses. The builder may want protection for the aircraft and personal liability while the operator has concerns about personal or professional exposure. Those interests can be related without being identical.

Use a Ground Run Role Matrix

The matrix helps organize the request. It does not establish required licenses or technical procedures for conducting an engine run. Those questions belong with qualified technical and regulatory guidance.

Review the Aircraft Policy for the Planned Activity

Obtain the actual policy and endorsements rather than relying on a statement that the project has ground insurance. Identify how the contract treats construction testing engine operation movement and flight. Use the definitions supplied by the policy, not assumptions based on the aircraft remaining stationary.

Ask whether the current arrangement accepts the other operator and whether any conditions need to be satisfied before the event. If an endorsement or updated placement is needed, retain evidence of the accepted effective terms. A pending request is not the same as an issued change.

The Global Aerospace experimental insurance discussion illustrates why a project changing stages merits review. Its descriptions should not be treated as universal policy definitions. The answer for your ground run must come from the actual contract and accepted facts.

Review the Operator Own Insurance Without Assuming It Replaces Yours

A mechanic or other professional may have business insurance relevant to the work. Ask for the information needed to understand the arrangement, including the insured business and activity. A certificate alone does not establish that every loss involving your aircraft will be paid by that policy.

Do not cancel or reduce owner's protection simply because the other person says they are insured. Their coverage may address legal liability or specified professional activities rather than serving as direct physical damage insurance for your project. Actual policy language and facts determine the result.

The person conducting the run should also understand whether your policy protects them. Avoid promising that they are fully covered because they are helping with your aircraft. If they want their own insurance reviewed, treat that as a separate request with the activity accurately disclosed.

Read Work Orders and Agreements Before Signing

A work order may contain responsibility for damage, indemnity, liability limitations or other obligations. Obtain the complete document and have legal counsel review questions about its effect. Send the relevant provisions for insurance review rather than relying on the agreement title.

A contract allocating responsibility does not automatically amend either party policy. Someone agreeing to pay for damage does not establish that their insurer accepted that obligation, and a waiver does not tell you the full extent of remaining protection.

Keep the final signed version and any accepted insurance changes together. If the operator asks for new terms after the review, identify what changed. The file should show the arrangement actually used, not an earlier draft everyone assumes remained unchanged.

Confirm Location and Any Aircraft Movement

Identify the place where the run will occur and whether the aircraft must be transported or moved there. Another person performing the work may also mean the project changes custody or location. Those are additional facts for the submission.

Separate a stationary run from taxiing. If movement may be part of the plan, disclose it before the event and review the applicable terms. Avoid a fallback plan in which the group decides on the day to add a taxi test without checking whether the insurance arrangement fits.

Facility requirements also deserve review. Provide relevant hangar or airport agreements and identify any requested insured parties. The owner should understand which requests are supported by the actual policy rather than assuming a facility certificate creates the requested protection.

A Hypothetical Mechanic Assisted Run

Imagine a builder asking a mechanic employed by a local shop to operate the controls during a stationary ground run at the airport. The builder will observe and record information. The shop supplies a work order. This is a planning example and not a customer account or coverage promise.

The builder sends the operator identity, employer, work scope, location and work order for review. The owner's policy activity and operator conditions are considered separately from the shop's insurance. The group records whether any movement is planned and what changes would require another review.

Later, the shop proposes using a different employee and conducting a short taxi test. Those are new facts. The builder returns them to the review process rather than assuming an earlier discussion about the original stationary run resolved a different person and activity.

Create a Clear Written Request

A useful message states the aircraft, project stage, current policy, proposed date, location and person performing the run. Describe the exact activity in plain language and attach the work agreement if one exists. Ask for identification of the terms and conditions that apply.

Avoid asking only whether a friend is covered. That question can mean owner hull protection, personal liability, professional liability or injury protection. State which interest you want reviewed so the response is specific enough to use.

Our experimental aircraft insurance page provides the broader project coverage context. Keep the immediate request focused on another person performing this ground run, including any contract, custody or movement changes.

Before Another Person Performs the Run

• Identify the individual and any business through which they are working.
• Describe control operation supervision maintenance and movement separately.
• Provide the requested experience and qualification information.
• Review owner's protection and operator's protection as different questions.
• Compare the work agreement with the actual insurance arrangement.
• Disclose location custody and transport changes.
• Retain accepted terms and complete conditions before the event.
• Return changed people or activities for review before proceeding.

Frequently Asked Questions

Can a Friend Perform the Run Under My Policy?

Review the actual person activity and policy. Friendship does not establish insured status or satisfaction of conditions. Describe what the friend will do and ask separately about protection for you your aircraft and the person conducting the run.

Does the Operator Need to Be a Named Pilot?

The answer depends on the policy and activity. Do not assume a pilot provision is irrelevant or automatically satisfied because the aircraft will remain on the ground. Have the applicable wording identified with the planned operation disclosed.

Is a Mechanic's Certificate Enough for Insurance?

Qualifications can be relevant but they do not independently amend a policy. Provide the person experience and role and review the applicable conditions. Technical authority to perform work and insurance protection are separate questions that both need appropriate attention.

Will the Shop's Insurance Pay if the Project Is Damaged?

Do not promise that result. Review what the shop's insurance addresses and what facts would be required for a covered claim. The owner should retain an appropriate project insurance review rather than relying on the existence of a vendor certificate.

Should the Operator Be Added as an Additional Insured?

That is a specific coverage request requiring review of the relationship and intended protection. Do not use the designation as a universal solution. Identify the exposure the person wants addressed and compare the offered wording with that request.

What If We Change Operators on the Day?

Provide the new person details and obtain the necessary review before relying on the earlier arrangement. The accepted terms may be tied to named people qualifications or activities. A scheduling substitution should not silently become an unreviewed insurance change.
