Flight Chain App gives you every NTSB aviation accident report in your pocket for convenient, mobile-friendly access.

Flight Chain App also gives you these additional exclusive features to help you get more value out of NTSB reports, and make your time spent reading accident reports more productive:

• Accident Chains
See a visual representation of the chain of events.

• Trends
Discover and read NTSB reports by trend and type.

• Safety Quiz
Quiz yourself with questions based on actual NTSB accident reports.

Most aircraft accidents are caused by a chain of events rather than just one error. Reading accident reports helps you learn what not to do.

The more aviation accident reports you read, the more you'll know what not to do when you find yourself in similar scenarios.

We were surprised by a flight instructor's observation who, after more than 40 years of flying, was amazed at how many pilots of various experience levels aren't aware of the value of NTSB reports.

We also kept hearing a common theme among pilots: the NTSB website isn't the friendliest to use, especially on mobile.

Flight Chain App makes your flying life easier by giving you accident info that's quicker to digest. More convenient and less frustrating. For both you and your iOS device. Now with full support for Dark Mode too.

• Simplifies Reports
Helps you see and understand the accident chain.

• Convenient
NTSB accident reports by month in your pocket for easy access.

• Educate yourself
See accident trends and quiz yourself based on NTSB accidents.

• Aircraft buyers & brokers can use it when researching aircraft purchases. Convenient when you're on location and need to look up N-numbers.

Features that come with your one-time purchase app download include the following.

Version 1.15:

• Flight Chain App now fully support Dark Mode. Thanks for your patience while we took time in the real world to get in some IFR study for an instrument rating.

• Additional performance improvements under the cowling are included in this release to bring the app up to par for iOS 14 changes.

Awaiting NTSB Report

While not an avid user of this app, should they gain access and post the NTSB report for my brothers very unfortunate crash that killed him, along with his son, my nephew, a little over a year ago, I will be very grateful. That is all I am waiting on. I am not a pilot, nor aspire to be, I just want to see the NTSB report for this crash and was told this would be a great resource. While the app tells you that investigations of plane crashes can take up to a year, I hope they are being truthful. It’s been over a year now. May 31, 2018 is when they crashed, upon takeoff, out of Midland International Airport. I just want to see the report. So far it has not been posted in the app, but we just reached the one year benchmark and we all know how these organizations drag their feet...I just hope to see it soon.

Developer Response ,

We're so sorry to hear of your loss in that accident. Based on your comment, we presume you're referring to the Cirrus SR22 accident, aircraft tail number N670SR, at Midland International Airport last year. As of the date we're writing this response (June 21, 2019), the NTSB has only published a preliminary report (dated June 5, 2018), and that preliminary report is the only information we have at this time appearing in Flight Chain App for this accident. According to the NTSB, which is the source of all aviation accident reports: "Probable cause is the factor or factors that, based on all available evidence, the [NTSB] Board concludes most likely resulted in the accident. It generally takes around a year to produce a final report, which includes a probable cause and contributing factors." [ Source: ] That said, we have seen some NTSB accident reports where a final report detailing the probable cause seems to take much longer than a year to get issued, and in some cases, never gets issued. Hopefully that won't be the case with this accident, but it is up to the NTSB to determine when they issue a final report on any given accident. We hope this information helps.

Font colors need changing!

Hi guys, this app is great! However there are white text on white background and black text on black background so it makes it hard to use when trying to filter. If you could take a look into this bug and have it fixed it would be greatly appreciated. Thanks!!

Developer Response ,

Thanks for your review and comment! Happy to hear you like Flight Chain App. As of version 1.15 (released on March 7, 2021), Flight Chain App now fully support Dark Mode, and this problem of certain font colors on similar backgrounds should now be resolved.

Not helpful unless you pay monthly fee

The app doesn’t really do anything a quick google search won’t tell you unless you pay the monthly fee for the premium service. Kind of a disappointment.

Developer Response ,


We wanted to let you know that, beginning with our version 1.14 release, we discontinued the optional in-app purchase subscription plans (formerly known as 'Plus' and 'Expert').

Additional user feedback like yours told us that subscriptions were not well received and they limited the usefulness of the app for the majority of users. As a result, they were a hindrance to our goal of providing more safety information to more pilots.

Starting with this version 1.14 app update, all features that were associated with the former 'Plus' and 'Expert' plans are now available to all users who have downloaded the app.

(For users who did purchase an optional subscription plan, their subscription should automatically cancel at the end of the current billing cycle, they should not be billed again by Apple's payment system, and with the version 1.14 app update they will still have access to all features of the app after it cancels.) ####

PREVIOUS RESPONSE 1/9/2019 -- Thank you! We appreciate you taking the time to let us know your thoughts. You are right that some of the content in the app can be found via Google searches. One of the app's goals is to package all that up in a convenient mobile app format to help save you time so you don't have to cull through web searches. At the same time, the app brings some unique features of its own (viewing the accident chain so you can see the chain of events, viewing accident trends and reading NTSB reports by trend to better understand how certain types of accidents happen, providing safety tips that relate to a given accident report, to name a few). The nominal monthly fee helps ensure we can continue providing this service to the aviation ccommunity. Stay tuned for more app updates in 2019. We have plans in the coming months to release additional features to add more value, some of which won't require a monthly fee. If you have further feedback on what would make the app more valuable for you, please let us know by sending a support ticket from within the app so we can continue making improvements. Thanks!
