Narrative:

The problem arose when I changed from category a to category B aircraft and relied on previous experience and observation of 2- and 4-ENGINED turbine aircraft using the facility. The problem was discovered, after landing, when the FBO informed me that certain category B aircraft were prohibited. (The same person said nothing of this while I was in the pattern and communicating with him.) contributing factors were: 1) failure to study the airport diagram for unusual notes. 2) more than 100 previous operations at this facility in a category a aircraft. 3) observation of 2- and 4-ENGINED turbine aircraft operating at the facility. 4) category a and B IFR operations information on the approach plates. 5) no similar information in commercial airport directory. 6) no query from ATC or FBO prior to landing. Corrective actions: thorough study of airport diagrams for unusual features. Request assistance from approach controllers in questionable situations. I feel that in situations such as this, ATC, although not primarily responsible, should be informed and assist in preventing similar incidents if it is a safety problem.

Original NASA ASRS Text

Title: SMA TWIN CLASSIFIED CATEGORY B LANDS AT ARPT CLOSED FOR THAT CATEGORY.

Narrative: THE PROBLEM AROSE WHEN I CHANGED FROM CATEGORY A TO CATEGORY B ACFT AND RELIED ON PREVIOUS EXPERIENCE AND OBSERVATION OF 2- AND 4-ENGINED TURBINE ACFT USING THE FACILITY. THE PROBLEM WAS DISCOVERED, AFTER LNDG, WHEN THE FBO INFORMED ME THAT CERTAIN CATEGORY B ACFT WERE PROHIBITED. (THE SAME PERSON SAID NOTHING OF THIS WHILE I WAS IN THE PATTERN AND COMMUNICATING WITH HIM.) CONTRIBUTING FACTORS WERE: 1) FAILURE TO STUDY THE ARPT DIAGRAM FOR UNUSUAL NOTES. 2) MORE THAN 100 PREVIOUS OPERATIONS AT THIS FACILITY IN A CATEGORY A ACFT. 3) OBSERVATION OF 2- AND 4-ENGINED TURBINE ACFT OPERATING AT THE FACILITY. 4) CATEGORY A AND B IFR OPERATIONS INFO ON THE APCH PLATES. 5) NO SIMILAR INFO IN COMMERCIAL ARPT DIRECTORY. 6) NO QUERY FROM ATC OR FBO PRIOR TO LNDG. CORRECTIVE ACTIONS: THOROUGH STUDY OF ARPT DIAGRAMS FOR UNUSUAL FEATURES. REQUEST ASSISTANCE FROM APCH CTLRS IN QUESTIONABLE SITUATIONS. I FEEL THAT IN SITUATIONS SUCH AS THIS, ATC, ALTHOUGH NOT PRIMARILY RESPONSIBLE, SHOULD BE INFORMED AND ASSIST IN PREVENTING SIMILAR INCIDENTS IF IT IS A SAFETY PROBLEM.
