Limitations and Conditions: Vent windows P/N’s B-1308, and -1 and -2 are not to be opened above 145 MPH. If an alternate static source is installed in the cockpit, it is not to be used with the vent windows open. The approval of this change in type design applies basically to Beech Models 50 (L-23A), B50 (L-23B), C50, D50 (L-23E), D50A, D50B, D50C, D50E, E50 (L-23D, RL-23D), F50, G50, H50, J50 only.
