Narrative:

Aircraft while on final approach segment and after encountering severe windshear/wake turbulence, passenger on board became visibly irritated and started being incoherent using profanities at the pilot. The referred individual along with a companion was placed on seat #5 (2 rows behind pilot's seat) with a warning to fasten his seatbelt and remain seated throughout the flight. This individual was a member of the party five of boarding the aircraft. The referred individual jumped forward, upset by the unusual abrupt pitch attitude of the aircraft, and tried to attack the pilot. What followed was a struggle with some of his companions that were trying to subdue him. Being in such a critical threatening situation and on final approach for landing, the pilot declared an emergency calling for the security support at the airport. Before boarding, pilot was unable to determine the individual conditions. Pilot not being an expert in intoxication behavior could not establish criteria for go-no-go situation. The referred individual appeared to have consumed alcohol beverages. The contributing factor to this incident rests only with the fact that referred individual was under alcohol intoxication. I suggest crewmembers and ground crews work together to determine boarding for such passengers. The place and time for denying boarding should be made at the ticket counters, inside the airport premises, and not on the ramp, by the airplane.

Title: DISTRAUGHT PASSENGER APPARENTLY UNDER INFLUENCE OF ALCOHOL ATTACKED PLT OF SMT.

Narrative: ACFT WHILE ON FINAL APCH SEGMENT AND AFTER ENCOUNTERING SEVERE WINDSHEAR/WAKE TURBULENCE, PASSENGER ON BOARD BECAME VISIBLY IRRITATED AND STARTED BEING INCOHERENT USING PROFANITIES AT THE PLT. THE REFERRED INDIVIDUAL ALONG WITH A COMPANION WAS PLACED ON SEAT #5 (2 ROWS BEHIND PLT'S SEAT) WITH A WARNING TO FASTEN HIS SEATBELT AND REMAIN SEATED THROUGHOUT THE FLIGHT. THIS INDIVIDUAL WAS A MEMBER OF THE PARTY FIVE OF BOARDING THE ACFT. THE REFERRED INDIVIDUAL JUMPED FORWARD, UPSET BY THE UNUSUAL ABRUPT PITCH ATTITUDE OF THE ACFT, AND TRIED TO ATTACK THE PLT. WHAT FOLLOWED WAS A STRUGGLE WITH SOME OF HIS COMPANIONS THAT WERE TRYING TO SUBDUE HIM. BEING IN SUCH A CRITICAL THREATENING SITUATION AND ON FINAL APCH FOR LANDING, THE PLT DECLARED AN EMER CALLING FOR THE SECURITY SUPPORT AT THE ARPT. BEFORE BOARDING, PLT WAS UNABLE TO DETERMINE THE INDIVIDUAL CONDITIONS. PLT NOT BEING AN EXPERT IN INTOXICATION BEHAVIOR COULD NOT ESTABLISH CRITERIA FOR GO-NO-GO SITUATION. THE REFERRED INDIVIDUAL APPEARED TO HAVE CONSUMED ALCOHOL BEVERAGES. THE CONTRIBUTING FACTOR TO THIS INCIDENT RESTS ONLY WITH THE FACT THAT REFERRED INDIVIDUAL WAS UNDER ALCOHOL INTOXICATION. I SUGGEST CREWMEMBERS AND GND CREWS WORK TOGETHER TO DETERMINE BOARDING FOR SUCH PASSENGERS. THE PLACE AND TIME FOR DENYING BOARDING SHOULD BE MADE AT THE TICKET COUNTERS, INSIDE THE ARPT PREMISES, AND NOT ON THE RAMP, BY THE AIRPLANE.
