Raytheon Aircraft Company Beech Models 1900, 1900C, and 1900D Airplanes
The following airplane models and serial numbers that are certificated in any category and are required to have a cockpit voice recorder (CVR) installed:
| Models | Serial No. |
|---|---|
| 1900 and 1900C | All serial number airplanes with the applicable Raytheon Aircraft Company (RAC) Kit No. 114-3020 variation (−1, −3, −7, or −9) incorporated. |
| 1900 and 1900C | All serial number airplanes with RAC Kit No. 114-3032-1 incorporated. |
| 1900 and 1900C | All serial number airplanes with RAC Kit No. 114-3008-1 incorporated. |
| 1900 and 1900C | All serial number airplanes where RAC installed the CVR. |
| 1900D | UE-1 through UE-376. |
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Models 1900, 1900C, and 1900D airplanes. This AD requires you to modify the cockpit voice recorder (CVR) system. This AD is the result of instances where the recording quality of the CVR in the affected airplanes was so poor that the information was practically unrecoverable. The actions specified by this AD are intended to correct substandard quality cockpit voice recordings caused by the configuration of the present CVR system, which could affect air safety if important information that the CVR provides is not available after an accident. This information helps determine the probable cause of an accident and aids in developing necessary corrective action or design changes to prevent future accidents.
To address this problem, you must accomplish the following:
| Action | Compliance time | Procedures |
|---|---|---|
| (1) Accomplish the CVR system modifications specified in Raytheon Recommended Servcie Bulletin SB 23-3094, Issued: November, 1999 | Within 12 months after the effective date of this AD | Do the modifications in accordance with procedures in the ACCOMPLISHMENT INSTRUCTIONS section of Raytheon Recommended Service bulletin SB 23-3094, Issued: November, 1999. |
| (2) Do not install a CVR on any of the affected airplanes without incorporating the modifications required by paragraph (d)(1) of this AD | As of the effective date of this AD | Not Applicable. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
