Narrative:

WX conditions at time of incident: 600 ft and 3.5 mi. As I was beaching in from an offshore helicopter flight at pass cavallo, preparatory to landing at port O'connor, tx. A cessna appeared out of the clouds northeast bound at about 600 ft. As I was at 500 ft, evasive action was required to prevent a midair collision. Nearest approach was 1/4 mi. The current houston sectional aeronautical chart (expires jul/xx/95) warns of extensive helicopter activity near port O'connor and advises pilots to monitor 131.05. The current hsac (helicopter safety advisory conference) frequency chart lists 122.90 as the frequency to use within 10 NM of port O'connor. Transiting civilian and military aircraft should be encouraged to report position and intentions if within 10 NM and below 1200 ft of these gulf coast areas of extensive helicopter activity. Better coordination with FAA and NOAA and the hsac could prevent a midair collision in the future. It would even be better if part 135 helicopters were required to have traffic warning equipment.

Title: POTENTIAL CONFLICT BTWN A CESSNA TYPE ACFT AND ROTARY WINGED TFC.

Narrative: WX CONDITIONS AT TIME OF INCIDENT: 600 FT AND 3.5 MI. AS I WAS BEACHING IN FROM AN OFFSHORE HELI FLT AT PASS CAVALLO, PREPARATORY TO LNDG AT PORT O'CONNOR, TX. A CESSNA APPEARED OUT OF THE CLOUDS NE BOUND AT ABOUT 600 FT. AS I WAS AT 500 FT, EVASIVE ACTION WAS REQUIRED TO PREVENT A MIDAIR COLLISION. NEAREST APCH WAS 1/4 MI. THE CURRENT HOUSTON SECTIONAL AERO CHART (EXPIRES JUL/XX/95) WARNS OF EXTENSIVE HELI ACTIVITY NEAR PORT O'CONNOR AND ADVISES PLTS TO MONITOR 131.05. THE CURRENT HSAC (HELI SAFETY ADVISORY CONFERENCE) FREQ CHART LISTS 122.90 AS THE FREQ TO USE WITHIN 10 NM OF PORT O'CONNOR. TRANSITING CIVILIAN AND MIL ACFT SHOULD BE ENCOURAGED TO RPT POS AND INTENTIONS IF WITHIN 10 NM AND BELOW 1200 FT OF THESE GULF COAST AREAS OF EXTENSIVE HELI ACTIVITY. BETTER COORD WITH FAA AND NOAA AND THE HSAC COULD PREVENT A MIDAIR COLLISION IN THE FUTURE. IT WOULD EVEN BE BETTER IF PART 135 HELIS WERE REQUIRED TO HAVE TFC WARNING EQUIP.
