6. Web-Based Operations Safety System (WebOPSS) Insurance Viewing Tools. WebOPSS provides several tools for
viewing aircraft accident liability insurance coverage information. For additional information about the WebOPSS features discussed below,
refer to the WebOPSS CHDO User Guide available under the Tools menu.
a. Maintain Operator DataInsurance. The WebOPSS Maintain Operator Data > Insurance view allows
inspectors to review the status of the air carrier’s aircraft accident liability insurance. The Insurance view displays information
about the current insurance policy(s) and policy status for the air carrier. Selecting the link to a policy number will display the aircraft
covered on that policy. Policies with blanket coverage indicated apply to all aircraft operated by the air carrier.
Figure 1. Maintain Operator DataInsurance View
b. Insurance Viewer Report. WebOPSS provides a report of aircraft accident liability
insurance coverage information under Tools > Reports > Standard, Insurance Viewer. The report can be run on a specific operator designator
code, by the responsible Flight Standards office, and/or by the operating CFR part. The results report lists the insurance policy information
filed using OST Form 6410 or 6411 for the air carrier. Selecting the link to a Policy Number will display the history of the policy filings.
Selecting the number in the Insured Aircraft column will display the aircraft make, model, and series (M/M/S); registration numbers; and serial
numbers covered on the corresponding policies. Selecting the number in the Uninsured Aircraft column will display the aircraft M/M/S, registration
numbers, and serial numbers of the aircraft that do not have aircraft accident liability insurance on file with the Technical Programs Branch for
Note: The Uninsured Aircraft column label does not indicate the aircraft in question is not insured. It
signifies that the administrative filing requirement to have an OST Form 6410 or 6411 certificate of insurance identifying that aircraft on file
with the Technical Programs Branch has not been met.
Note: The Econ Authority column applies only to part
taxi operators and is not a true indication of other types of economic authority granted by the DOT.

c. Custom Reports. A number of additional custom reports are available to ASIs in
WebOPSS under Tools > Reports > Custom > Custom Reports folder > Insurance and Economic Authority folder, including a report
of aircraft without insurance coverage on file with the Technical Programs Branch.
7. Action. ASIs with oversight responsibilities for part
carriers should review the aircraft accident liability requirements discussed in this notice. To review aircraft insurance coverage in force and
on file with the Technical Programs Branch, ASIs can use the WebOPSS tools identified above.
a. No Evidence of Insurance Coverage. If aircraft do not have evidence of coverage in force and on file with
the Technical Programs Branch, ASIs should notify the air carrier to file an updated OST Form 6410 or 6411 not more than 30 days after the
effective date of the endorsements with the Technical Programs Branch to remedy the situation.
b. Insurance Endorsements. Per § 205.4(b), the air carrier has 30 days after the effective date to file
insurance endorsements. If a carrier provides the ASI with evidence that it has insurance in force but has yet to file a certificate of insurance
with the Technical Programs Branch, the ASI should inform the carrier to file updated insurance information using OST Form 6410 or 6411 within
30 days of the effective date of the endorsement. The ASI may add the covered aircraft to the carrier’s OpSpecs provided the carrier commits
to filing and providing the ASI with evidence of such filing within 30 days. Evidence of filing is:
(1) A copy of the OST Form date-stamped by the Air Transportation Division (must be requested from the Technical
(2) An email from
the filing (must be requested from the Technical Programs Branch), or
