मैं,मेरा अस्तित्व और सनातन

आज जब बात चली तो ये कहने में या यू कहे कि स्वीकार करने में कोई गुरेज नहीं है कि हम अधिकांश हिन्दू कॉयर,मतलबी और बुजदिल होते हैं।  ये कोई नई बात नहीं है। हजारों साल से चल रहा है।

ये तो अपने इष्ट पर भी मजाक बनाते है और गर्व से बनते देखते रहते है।

आप अपने यहां का ही उदाहरण देख लिजिये।

5 हिन्दू परिवार ने मिलकर काम करने वाले मजदूरों को धमका दिया कि तुम मंदिर में काम नहीं करोगे।

ये कौन लोग है? सभी हिन्दू ही है या फिर इनके पूर्वज मुसलमान रहे होंगे।

हैरानी है फिर भी सनातन का अस्तित्व है।

हम लोग बहुत सारे पंथ, गुरुओं के शिष्य और अपने विचारों के गुलाम होकर रह गये है।यही विचार और पंथ हमें अपने ही सनातन से दूर किये जा रहा है इतना कि हमें अपने धर्म के लिए आवाज़ उठाने की हिम्मत ही नहीं रही।

रही बात इंद्रप्रस्थ कि तो अभी की सरकार ने अब जाकर इतिहास के पन्नों से मुगलो का 

गुणगान हटाने की हिम्मत तो की है।अब आगे देखिये क्या होता हैं।शायद कल दिल्ली फिर से इंद्रप्रस्थ के नाम से जाना जाने लगेगा।पर तब हम न हो लेकिन आशा है सनातन तब भी होगा।

हमे अलग अलग संप्रदाय और गुटों में बांटने का जितना जाती प्रथा का हाथ रहा है उतना ही हमारे धर्म गुरुओं का भी रहा है। गुरुओं ने हमेशा ही अपने विचार को अपने शिष्यों पर थोपने की कोशिश की और डर से या और तरीके से उन्हें सनातन से अलग हट कर सोचने के लिए विवश किया।कभी ये नहीं कहा कि जिन विचारों से मै आपको अवगत करा रहा हु वो सनातन से ही आया हैं।

सनातन के पतन के जिम्मेदार दोनों ही है।

THS Actuator jamming operational check

THS Actuator jamming operational check

Access platform-20Feet

Open the panel-312AR

Jamming Tool-0U190857

Feeler gauge -1.2mm

Lock wire-14QEB1(.6mm)

Minimum Two persons -One in cockpit and one in THS Compartments 

AMM Reference-

27-44-00-710–001-A

Lockwired caps marked in the RED BOX above in the picture are to be cut and removed to install a Jamming Tool(shown in pic below)on the shaft spline of the control shaft.

THS Jamming Test:-

Four Tests are to be done

(1)Elec.Mode RH VALVE BLOCK- TOOL MARKS A/C N UP,

(2)Elec.Test LH VALVE BLOCK- TOOL MARKS A/C N UP,

(3)Mech Mode LH VALVE BLOCK-LH A/C N DN,

(4)Mech Mode,RH VALVE BLOCK-RH A/C N DN 

Gap to be checked between input plate and Ball carrier.This is behind the valve control Shaft.Gap must not be exceeding 1.2mm.

Reference mark is on the control valve detent.

Step 1:-

Alignment of the Left and Right control Valve detents:-

Put one end of the Jamming tool on the splined end of the Valve control shaft,

Use the tool side N UP or N DN  mark of the Jamming tool that puts the spigot nearest to the recess,

Turn the mechanical input of the THS ACTUATOR until the jamming tool goes into the recess.

If the Jamming tool is installed with the side LH or RH with A/C N DN marks,turn the mechanical input clockwise until the detent is centred with a click sound.

If the Jamming tool is installed with the LH or RH with A/C N.UP Marks,turn the mechanical input CCW until the detent is centred with a click sound.

If it is not centred then turn the mechanical input until you get Click 

sound.

Step 2:-Depressurised the hydraulic and ELAC 1,SEC1 ON 23VU & ELAC2 &SEC 2 are released so that OFF light comes ON.

Now,follow AMM TASK for the test procedures.

Once all  the four  tests are performed,normalised the Aircraft.
