Narrative:

During taxi out for takeoff on runway 9, I turned into taxiway a bypass west taxiway B. The tower said to continue down runway, but we were entering the taxiway and it was too late to stop and safely turn back onto runway. The taxi clearance was back taxi runway 9. An air carrier Y 757 departed just prior to us. He was doing a taxi clearance of 'back taxi runway 9.' just before flight air carrier Y passed the taxiway, the tower instructed him to turn right off the runway and use taxiway a/B. The previous air carrier Y departure was also a 757 and we observed their taxi via taxiway a/B to runway 9. The problem arises that I didn't realize/remember until the next day, while deadheading to home base, that we taxied on a taxiway not stressed for widebody transport aircraft. I referred back to our operations pages issued, and in the general section the notes on runway restrs and taxiway restrs. 'Taxiway a-b not stressed for widebody transport aircraft.' our aircraft, an A-300/600R, was operating at 305000 pounds for that takeoff, some 80000-100000 pounds heavier than the 757's that preceded us. I reviewed the notes prior to landing, and 2 hours later for departure read only departure notes and special departure procedure page for the A-300 out of st maarten. Neither section made any mention to the taxiway restrs. My recommendation to our company is to limit general notes to company frequency, special customs instructions, airport procedures, security, etc, specifies to landing and departing under those sections and pages. The st maarten airport should have a sign up for a friendly reminder next to taxiway a/B entrances -- 'no widebody transport taxi' to prevent further incidents.

Title: FLC OF A WDB TAXIED ON A TXWY NOT STRESSED FOR THEIR ACFT.

Narrative: DURING TAXI OUT FOR TKOF ON RWY 9, I TURNED INTO TXWY A BYPASS W TXWY B. THE TWR SAID TO CONTINUE DOWN RWY, BUT WE WERE ENTERING THE TXWY AND IT WAS TOO LATE TO STOP AND SAFELY TURN BACK ONTO RWY. THE TAXI CLRNC WAS BACK TAXI RWY 9. AN ACR Y 757 DEPARTED JUST PRIOR TO US. HE WAS DOING A TAXI CLRNC OF 'BACK TAXI RWY 9.' JUST BEFORE FLT ACR Y PASSED THE TXWY, THE TWR INSTRUCTED HIM TO TURN R OFF THE RWY AND USE TXWY A/B. THE PREVIOUS ACR Y DEP WAS ALSO A 757 AND WE OBSERVED THEIR TAXI VIA TXWY A/B TO RWY 9. THE PROB ARISES THAT I DIDN'T REALIZE/REMEMBER UNTIL THE NEXT DAY, WHILE DEADHEADING TO HOME BASE, THAT WE TAXIED ON A TXWY NOT STRESSED FOR WDB ACFT. I REFERRED BACK TO OUR OPS PAGES ISSUED, AND IN THE GENERAL SECTION THE NOTES ON RWY RESTRS AND TXWY RESTRS. 'TXWY A-B NOT STRESSED FOR WDB ACFT.' OUR ACFT, AN A-300/600R, WAS OPERATING AT 305000 LBS FOR THAT TKOF, SOME 80000-100000 LBS HEAVIER THAN THE 757'S THAT PRECEDED US. I REVIEWED THE NOTES PRIOR TO LNDG, AND 2 HRS LATER FOR DEP READ ONLY DEP NOTES AND SPECIAL DEP PROC PAGE FOR THE A-300 OUT OF ST MAARTEN. NEITHER SECTION MADE ANY MENTION TO THE TXWY RESTRS. MY RECOMMENDATION TO OUR COMPANY IS TO LIMIT GENERAL NOTES TO COMPANY FREQ, SPECIAL CUSTOMS INSTRUCTIONS, ARPT PROCS, SECURITY, ETC, SPECIFIES TO LNDG AND DEPARTING UNDER THOSE SECTIONS AND PAGES. THE ST MAARTEN ARPT SHOULD HAVE A SIGN UP FOR A FRIENDLY REMINDER NEXT TO TXWY A/B ENTRANCES -- 'NO WDB TAXI' TO PREVENT FURTHER INCIDENTS.
