Narrative:

On departure out of juneau, ak, we encountered severe turbulence and windshear on initial climb through approximately 1500 ft MSL. We had to 'firewall' the power and lower the nose attitude of the aircraft to regain control. Shortly thereafter, we had to again 'firewall' the power to keep the aircraft climbing and speed from decreasing. In retrospect it is always easy to look back and second guess your actions or play 'mon morning quarterback,' but some of the things we may have done are: delay the takeoff until winds/conditions subsided. A more thorough 'windshear' takeoff briefing to include anticipated actions, etc. Abort the takeoff. Stress windshear recognition/avoidance during annual recurrent training and simulator checks. In conclusion, the experience of the captain and working as a crew combined with the excellent company training received we were able to prevent a near disaster and live to report it.

Title: FLC OF ACR ACFT MOMENTARILY LOST CTL DURING INITIAL CLB OUT DUE TO WIND SHEAR.

Narrative: ON DEP OUT OF JUNEAU, AK, WE ENCOUNTERED SEVERE TURB AND WINDSHEAR ON INITIAL CLB THROUGH APPROX 1500 FT MSL. WE HAD TO 'FIREWALL' THE PWR AND LOWER THE NOSE ATTITUDE OF THE ACFT TO REGAIN CTL. SHORTLY THEREAFTER, WE HAD TO AGAIN 'FIREWALL' THE PWR TO KEEP THE ACFT CLBING AND SPD FROM DECREASING. IN RETROSPECT IT IS ALWAYS EASY TO LOOK BACK AND SECOND GUESS YOUR ACTIONS OR PLAY 'MON MORNING QUARTERBACK,' BUT SOME OF THE THINGS WE MAY HAVE DONE ARE: DELAY THE TKOF UNTIL WINDS/CONDITIONS SUBSIDED. A MORE THOROUGH 'WINDSHEAR' TKOF BRIEFING TO INCLUDE ANTICIPATED ACTIONS, ETC. ABORT THE TKOF. STRESS WINDSHEAR RECOGNITION/AVOIDANCE DURING ANNUAL RECURRENT TRAINING AND SIMULATOR CHKS. IN CONCLUSION, THE EXPERIENCE OF THE CAPT AND WORKING AS A CREW COMBINED WITH THE EXCELLENT COMPANY TRAINING RECEIVED WE WERE ABLE TO PREVENT A NEAR DISASTER AND LIVE TO RPT IT.
