There shall be at least one drain hole to discharge or scavenge entrained liquid, such as rain or melted ice water. The probe design shall consider the effects of ingested solid particles such as ice, sand and dust. </p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p> 3.4.3</p> </td> <td bgcolor="#d9d9d9"><p> Page 3, replace Subsection 3.4.3 with the following text:</p> <p> 3.4.3 Mis-installation </p> <p>The probe shall incorporate design features to minimise the potential for mis-installation on the aircraft. For example, in the case where the probe contains multiple pneumatic or electrical connections these features may include the incorporation of different pneumatic fitting sizes or types, or different electrical connector keying. </p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p> <br/> </p> </td> <td bgcolor="#d9d9d9"><p> <br/> </p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p> 3.4.11</p> </td> <td bgcolor="#d9d9d9"><p> Page 4, amend 3.4.11 as follows:</p> <p> Protective coatings and finishes utilised in the construction of the probe shall not crack, chip, or scale to the extent that the probe no longer meets the aerodynamic accuracy requirements when exposed to the qualification test requirements of this standard.</p> <p>Other FAA modification not retained.</p> </td> </tr> <tr valign="top"> <td bgcolor="#d9d9d9"><p> 4.6</p> </td> <td bgcolor="#d9d9d9"><p> Page 7, amend 4.6 as follows:</p> <p>Other means can be used to demonstrate compliance with this requirement provided there is evidence they are equivalent or better than the specified test.
