NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE ORBITAL SCIENCES CORPORATION: REQUIRE, AS PART OF ELV LAUNCH PLANNING DOCUMENTATION: A COMMUNICATIONS PLAN THAT WOULD INCLUDE, AT A MINIMUM: A PROVISION THAT INTERPHONE OR OTHER COMMUNICATION ASSIGNMENTS BE APPORTIONED TO ALLOW DECISION MAKERS FROM EACH PARTY DIRECT ACCESS TO THE DECISION MAKERS OF OTHER PARTIES AND THE PROPER RADIO-TELEPHONE COMMUNICATION PHRASEOLOGY ARE USED, AND A PROVISION THAT KEY PARTICIPANTS IN THE LAUNCH MONITOR A COMMON INTERCOM CHANNEL AT AN ESTABLISHED POINT IN THE COUNTDOWN AND THAT THESE PARTICIPANTS CONTINUE TO MONITOR THIS CHANNEL DURING THE FINAL COUNTDOWN SEQUENCE AND AFTER LAUNCH.
In plain language (FlightFinder summary)
The NTSB asks Orbital Sciences Corporation to include in its launch planning documentation a communications plan requiring that interphone or radio assignments enable direct access among decision makers from all parties and that proper radio-telephone phraseology is used. It also requests a provision ensuring key launch participants monitor a common intercom channel at a specified point in the countdown and continue to do so during the final countdown and after launch.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
